Question

What expression is the simplified form of

Answer 1

Rules of exponents. Know what things like: \((x^m)^n\) mean?

Answer 2

\((x^m)^n=x^{m\cdot n}\)
\(\sqrt{x}=x^{\frac{1}{2}}\)

If we take those two together, it changes your problem to:
\((y^4)^{\frac{1}{2}}\) which should be pretty easy to solve.

Answer 3

i got d whitch is y^2 squared y
