    can you show 3(2k + 2 + 1) by adding values to left side (this should be ok because it's greater than) and then simply say 3(2k + 2 + 1) is greater than 2(k + 1) + 1 because our domain is positive integers and the same equation * 3 is greater than the one that's not

    i am so confused as to how and why inequality sign changed mid calculations.

      since 3^k is already >= , it would make sense that 3^(k+1)> . If K is greater then, then k+1 is definitely greater. While if K is equal to, then k+1 would also be greater, if this is what you ment.

    inequality n² ≤ 9 = 0,1,2 and 3 I know is -1, -2 and -3 but can someone explain it why or show me step by step

    can the base case be 0 that 3^0 = 1?

    6:42 the explanation for this makes no sense, you kept the multiplication of 3*1 in 2k+3 but you're free to throw away 3x2k? Where did it go? Why is one okay without the other?

    • @phoemi
      @phoemi Před rokem +1

      it's not an equation, he's showing that (3 * 2k + 3) > (2k + 3)

      For example, 3a > a when a is Z+.
