Re: Need help to prove
Hi;
You can not prove that because 2^4 = 4^2 and
2 ≠4
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi;
That is okay, asking a question is not disturbing.
