[tex]A(x)=3^2[/tex]
If 81 came out, what was dropped in?
I have rewritten the problem to [tex]3^x=81[/tex] but do not know how to solve it.

Sagot :

It is good equation. Look, that:
81 = 3 x 3 x 3 x 3 = 3^4.
So you have to solve:
3^x = 3^4 
exponents have to be the same, so
x=4
That's mean that A(4) = 81
