Great video â€â€
nice đđ
06:19 tiny error but great video.
Perfect theorem
Very nice explanation đ
ohter solution:
let a = 3^x - 4^x
the right side can be written as root(4^x)*root(a)
--> a = root(4^x)*root(a)
--> a - root(4^x)*root(a) = 0 with the comon factor root(a)
root(a)*[ root(a) - root(4^x) ]= 0
Solution 1: 1. factor = 0 --> root(a) = 0 --> 3^x - 4^x = 0 --> x = 0
Solution 2: 2. factor = 0 --> root(a) - root(4^x) = 0 --> 3^x =2*4^x --> x = log(2)/log(3/4)
0/0 is not 0 , it is undefined
good explaination
X= o is not possible.
wrong
0/0 is not 0 , it is undefined
wrong
