Answer:
Explanation:
To simplify the expression √49y^7, we can break it down as follows:
√49y^7 = √(7^2 * y^6 * y) = 7y^3√y
Therefore, the simplified expression is 7y^3√y.
Regarding the second expression, √14y, it is already simplified as the square root cannot be simplified further since 14 is not a perfect square. Thus, the expression remains as √14y.
