\[\large \sqrt[5]{128x^7y^25}=2xy^5\sqrt[5]{4x^2}\]
Recognize that 128 = 32*4, x^7 = x^5*x^2, and y^25= (y^5)^5
oops typo, \[\large \large \sqrt[5]{128x^7y^{25}}=2xy^5\sqrt[5]{4x^2}\]
what about this one?

thanks jim, that is correct.
\[\large \frac{\sqrt[3]{2y^4}}{\sqrt[3]{10x^4}}=\frac{y\sqrt[3]{25x^2y}}{5x^2}\]
Thanks! :)
