    \[\large \sqrt{y^9}= (y^9)^{1/2} = y^{9/2} = y^{4}\cdot y^{1/2}=~?\]

    You have your simplification already, \(\sf y^4 \cdot y^{1/2}\) \(y^{1/2}\) is written as the square root, therefore.. \[\boxed{\sqrt{y^9} =~ y^4\sqrt{y}} \]

    same thing but its better not to give the answer in square root form

    So if you understand square roots right, you'll know that for very 2 pairs of terms, only 1 will come out of the square root. therefore if you divide 9 by 1/2, you get 4.5, which is 4 1/2. y^4 means that 4 pairs of y came out of the square root, and you still have 1 left inside. 1 is half of 2, therefore it cannot come out of the square root.

    ok so my final answer with this is y^4 and sqr(y)

    Does that make more sense, @Knamzy ? And yes, that is your answer.
