Best ResponseYou've already chosen the best response.0You have your simplification already, \(\sf y^4 \cdot y^{1/2}\) \(y^{1/2}\) is written as the square root, therefore.. \[\boxed{\sqrt{y^9} =~ y^4\sqrt{y}} \]

Best ResponseYou've already chosen the best response.0same thing but its better not to give the answer in square root form

Best ResponseYou've already chosen the best response.0So 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.
