Best ResponseYou've already chosen the best response.01.)\[\ 3 \sqrt [5] {y^2}\]2.)\[\sqrt [5] {9y^2}\]3.)\[\sqrt [7] {a^4} * \sqrt [7] {\frac{1}{b^4}}\]4.)\[\sqrt [10] {a} * \sqrt [5] {\frac{1}{b}}\]

Best ResponseYou've already chosen the best response.0Here's an explanation for the first... \[3y^{2/5}=3*y^{2/5}\]Since the following is true...\[y^{1/5}= \sqrt [5] {y}\]The first statement is the same as...\[3*y^{1/5}*y^{1/5}=3*\sqrt[5]{y}*\sqrt[5]{y}=3\sqrt[5]{y^2}\]Does that make sense?
