Question

solve each equation for x  3^x =3^4 help

mathmate · Answer

$\large 3^x=3^4$
Noting that
$\large log_3(3^x)=x$ and $log_3(3^4)=4$
Take log to the base 3 on each side:
$\huge x=4$

@thegreatone215 
I suggest you review the rules of priorities of operations, commonly known as PEDMAS, or BEMDAS or some other variants.
Namely the order is parentheses, exponential, multiplication/division, THEN addition/subtraction.
What you wrote would mean
$5^2-2=25$ which give answer as $3\sqrt3$
But I suppose you actually mean:
$5^{x-2}=25$
which reduces to 
$5^{x-2}=5^2$
and you can solve this equation in a way similar to the first one.
