Are you asked to simplify those expressions? If so you need to know the 'laws of exponents' (which, I bet, are in your text):
\(\displaystyle a^xa^y= a^{x+y}\)
\(\displaystyle \frac{a^x}{a^y}= a^{x- y}\)
and
\(\displaystyle (a^x)^y= a^{xy}\)
\(\displaystyle a^xa^y= a^{x+y}\)
\(\displaystyle \frac{a^x}{a^y}= a^{x- y}\)
and
\(\displaystyle (a^x)^y= a^{xy}\)

(5y)2 /52y and (b2)8/(b5)3 Please help
Problem #1
If the expression is:
\(\displaystyle \dfrac{(5y)^2}{5^2y}\) it should be written as → (5y)2/(52y)
As written:
(5y)2 /52y means → \(\displaystyle \dfrac{(5y)^2}{5^2}y\)
Those parentheses in the denominators are super important. Those can change the result
