I was wondering of thsee simplifications are possible, log4(y) =log2^2(y) =log2(y)^2 OR logy since.log2^2 is 1. Thank you.so.much!

Hello, Tutu!
Very imaginative thinking . . . sadly, it doesn't work.
I was wondering of thsee simplifications are possible:
. .![]()
That last part is false: .does not equal
And the first part is false; we cannot move the "2" like that.
Compare: .
