    If you check your 'solution' in Python or the TI-Nspire CX calculator (both of which I checked) you will find that 1^x is 1, not 5. The problem with your solution is that you use some 'identities' that are not always true for complex numbers. In particular, it is not always true that ln(a^b) = b * ln(a) in the complex numbers. This is because the inverse "function" of e^x is a "multivalued function" with infinitely many results (usually), and to make it an actual function we choose just one of the results.
    The actual, usual definition of a^b in complex numbers is e^(b*ln(a)) where ln(a) is the principle logarithm of a and no other logarithm. The principle logarithm of 1 is just 0 (or 0 + 0i) so we always get
    1^x = e^(x*ln(1)) = e^(x*0) = e^0 = 1.
    You can never get 1^x = 5 unless you redefine complex exponentiation. The usual redefinition is to make it multivalued, in which case 5 would be one of the results of 1^x where x is your solution value.

      into Wolfram Alpha you get the answer 1.
      I'm also not sure what you mean by "take the 1/x power of both sides". Another "identity" that is not true in the complex numbers is (a^b)^c = a^(b*c). For example, check [(-1)^2]^(1/2) which is 1 versus (-1)^[2*1/2] which is -1. So it is not always true that (a^x)^(1/x) = a. I think that is what you are trying to do.
      To check a calculation you need to actually check the calculation from the beginning. Try 1^x for any complex value of x that you like. Doing anything else invites errors. That's what I teach my math students to: check the very first line, not later in the argument.

      Exp(i*2k*pi)=1*(cos(2k*pi) + i*sin(2k*pi)), so ln(exp(i*...))≠(i*...)*ln(e), but ln(exp(i*...))=ln(cos(2k*pi) + i*sin(2k*pi))=ln(cos(2k*pi))=ln(1)=0. Why? Because ln(exp(kx))=x*ln(k) is valid only for real nums. And for complex nums exp(z)=exp(x + iy)=r*(cosΩ + i*sinΩ), where r=sqrt(x**2 + y**2) & Ω=atan(y/x). And "length" of complex num or radius is r, while cosΩ + i*sinΩ is Ω-angle rotation of complex num radius on complex plain & radius of cosΩ + i*sinΩ is always 1

    Everything is possible in math, except your demonstration, which is false. When you modify an equation to find solution (what you does while taking ln of both parts), you should check the solution, which should here be rejected. In complex numbers, ln a = ln b does not imply a=b.

    The identity property of multiplication should be not used for assumption that 1^x = 5 because this mean that (1*a) it is not necessary equal (a). Therefore, number 1 shall be kept explicitly in multiplications. The full representation of imaginary is r*e^iθ. We have r=1. Therefore, the complex number from minute 8:00 of the presentation is not e^i2πk but 1*e^i2πk. Taking power of x, we have (1^x)(e^i2πkx), not just e^i2πkx. After taking Log we have ln(1^x) +i2πkx, not just i2πkx. Since 1^x = 5, the ln(1^x)=ln(5) and as not equal to zero ln(1^x) cannot be eliminated from the sum. ln(1^x)=0 makes further evaluations not valid.
    After assumption that 1^x=5, there is no place for (otherwise proper) assumption that 1^x=1.

    First I changed the notation and changed "x" to "z" to denote a complex number, and assume the general solution is z = x + iy. I also used a slight generalization of Euler's relation: exp(2nπi) = 1 for n = 0, ±1, ±2, ....
    Then I rewrite the problem as [exp(2nπi)]^z = 5 ⇒ Therefore we have two equations to deal with: Re{ [exp(2nπi)]^z} = 5 and Im{ [exp(2nπi)]^z} = 0
    I found solution of the second equation first ⇒ x = 0, ±1/2n, ±1/n, ±3/2n, ±2/n, ....
    The second equation leads to ±1/exp(2nπy) = 5. The negative signed cases are rejected since 5 can only be positive. Taking ln of both sides gives your solution for the imaginary part of z, y = -ln(5)/2nπ. However you seem to have missed the possible real parts of z: x = x = 0, ±1/2n, ±1/n, ±3/2n, ±2/n, ....

    Eg. for 1^i the results are = e^-2pi k. Now it is obvious that the res. in video is correct (just use the expr. for 1^i above).
    Of course, one should be aware what 1^z really means:
    This flow is wrong:
    1^z = 1^(x+iy) = 1^x 1^iy = 1^y^i = 1^i.

      @@methatis3013 You might be confusing some things:
      The task is to search for all x ∈ ℂ, such that 1^x = 5, so x is defined before you start transforming the given equation.
      Usually well known definitions are assumed to have been defined before we start the first transformation in an order to avoid referencing sth undefined; so real natural logarithm (ln), complex natural logarithm (Ln) and complex exponentiation are already defined prior to the task.
      Usually the definitions are given as follows (or similar):
      Let be z := r*e^(iα), r ∈ ℝ_0+, α ∈ ℝ, then we define complex Argument, complex natural logarithm and complex exponentiation as
      Arg(z) := (α + 2 π n) i,
      Ln(z) := ln(|z|) + i Arg(z) = ln(r) + (α + 2 π n) i,
      b^z := e^(z*Ln(b)), b, z ∈ ℂ.
      (I don't like using the same label for the complex and real natural logarithm.)
      It's not technically wrong per se, to repeat variable definitions (such as "There exists x such that for all k in Z:"), but I'm not sure that you understood that everytime you do that, you create a new variable that only shares the label(=name in this case) with the older ones, but are completely independent and different variables; that also comes with an implied scope, which is limited by implied parentheses.
      So when you write something like
      "∃ x: ∀ k ∈ ℤ: e^i2kxπ=5
      ∃ x: ∀ k ∈ ℤ: i2kπx=ln5
      ...",
      then that technically means:
      "∃ x: ∀ k ∈ ℤ: e^i2kxπ=5 (∃ x: ∀ k ∈ ℤ: i2kπx=ln5 ... )";
      note that within that parentheses you only can access the inner defined variables labeled with x and k, while the outer variables are different, despite the same name. And outside that parentheses, you cannot access the inner x and k, while the outer ones are used instead.
      But in this case it is unneccessary, to redefine the needed variables everytime we transform the equation.
      Because we silently assume that in the result x depends on k, the usual way is to define k first (to avoid variable x beeing equal to some undefined mathematcial object, though that's not really neccessary here):
      ∀ k ∈ ℤ, x ∈ ℂ : ( 1^x = 5
      e^(x*Ln(1)) = 5
      x*Ln(1) = ln(5)
      x = ln(5)/Ln(1)
      x = ln(5)/(ln(1) + (0 + 2 π k) i)
      x = - ln(5)/(2 π k) i
      )
      Note that this is also a massively shortened representation of the transformation; for example I didn't incorporate the definitions given above (which isn't really neccessary, while at the same time much nicer to read).
      Sidenote:
      The task is given somewhat imprecise, because it doesn't specify whether or not that 5 there is supposed to be a real number (which is the underlying assumption in the video) or a (representant of the) complex multivalue constant (representing that complex multivalue constant), in which case you might solve the task as follows instead:
      1^x = 5
      e^(x*Ln(1)) = e^Ln(5)
      e^(x*(ln(1)+i*2*k*π)) = e^(ln(5)+i*2*l*π)
      x*(i*2*k*π) = ln(5)+i*2*l*π
      x = l/k - ln(5)/(2*k*π) i

    But if you raise 1 to the 'solution' you found, you will still get 1, so you don't have a solution. Also, the very expression 1^x=5, when you take natural logarithms from both sides, is equivalent to ln(1)*x=ln(5), or 0=ln(5), which is a false equality. And any equation which is equivalent to an invalid equality or an illegal expression, is an invalid expression by itself, hence has no (real or complex) solutions.

    There are posted proofs that 1^x=3 and 1^x=5. Autor shall go little further: using the same method it can be proven that 1^x= y (where y >0). Then it will be possible to proof that any real number >0 is equal to any other real number >0. I wonder if this proof can be further extended to all real number (w/o or w/ ‘0’) and even extended to equality off all complex numbers. Than statement than "Everything is possible in math" is no longer valid--math no longer exists.
    Other option: please read my previous comment.

    Your mistake is making the leap from: e^(i.2k.pi) = 1
    to
    ( e^(i.2k.pi) )^x = 5
    1 to the power anything is still 1. Setting it = 5 doesn't make it valid. You could have set it = 1,000,000 and rearranged the equation to get x, but it would still be wrong.
    Plug your answer into the original question and the answer is still 1 not 5, as expected.

      @@ahojg no, it doesn't. Just because C allows for complex solutions (results of negative roots) doesn't extend the domain of a general function. This basically means that the square root of 1 is always 1, even in C. Because in C, the square root of -4 is always 2i, not -2i. This is obvious since the function of a variable x or z always has one value per x/z value.

    Too many missteps. First, as others have pointed out, taking the log of a complex isn't done correctly here.
    And restricting k to be an integer makes that equality incorrect.
    Indeed, here's a proof that 2=1.
    1^2 = 1.
    2^2 = 2 + 2
    3^2 = 3+3 + 3
    4^2 = 4 +4 + 4+ 4 .. . . . . .
    n^2= (n+n+n+......n) [n times]. upon differentiating,
    2n = (1 + 1 + 1 + 1+ . . . .) [ntimes[ or 2n = 1n = >

    *Infinite logs of unity (1 real and all the others complex/imaginary)*
    Trigonometric functions are periodic and exponential in complex numbers, so just like there are n nth roots of unity, similarly there are infinite logs of unity - 1 is real and all other log
    log(1) = 2 pi k i = 0 for k = 0 (the only real log of unity)
    There is only 1 real log of unity which is zero. All other logs of unity are imaginary numbers (i 2 pi K for K not equal to zero). So x = log(5) / log(1) = infinite complex (imaginary) numbers.
