Question

Myininya is here to help me with last problems~!

Answer 1

\[\large \sqrt[5]{128x^7y^25}=2xy^5\sqrt[5]{4x^2}\]

Answer 2

Recognize that 128 = 32*4, x^7 = x^5*x^2, and y^25= (y^5)^5

Answer 3

oops typo, \[\large \large \sqrt[5]{128x^7y^{25}}=2xy^5\sqrt[5]{4x^2}\]

Answer 4

what about this one?

Answer 5

thanks jim, that is correct.

Answer 6

\[\large \frac{\sqrt[3]{2y^4}}{\sqrt[3]{10x^4}}=\frac{y\sqrt[3]{25x^2y}}{5x^2}\]

Answer 7

Thanks! :)
