Question

(x^7/y^2)^8

Answer 1

\[(\frac{ x ^{7} }{ y ^{2} })^{8}\]
When we have a fraction elevated by an exponent, it's the same thing as elevating numerator and denominator by that same exponent:
\[\frac{ (x ^{7})^{8} }{ (y ^{2})^{8} }\]
Can you take over from there? :)

Answer 2

Do you multiply the exponents or add them?

Answer 3

Let's look at the property:
\[(a ^{n})^{m}=a ^{nm}\]
