√128x^7y^10
\[\sqrt{128x^7y^{10}}=\sqrt{2^7x^7y^{10}}\] is a start
I know my perfect square is 64 but not sure what to do with my odd exponents. It says "Assume all variables represent positive real numbers"
then see what comes outside of the radical two goes in to seven three times with a remainder of 1, so \(2^3\) comes out and a \(2\) stays in also for \(x\) it is the same \(x^3\) comes out, \(x\) stays in two goes in to ten five times with no remainder, \(y^5\) comes out
5th root of(128x^7y^10) = 5th root of(32*4 * (x^5)(x^2) * (y^10) = 5th root of((2^5)*4 * (x^5)(x^2) * (y^2)^5) = 2xy^2 (5th root of(4x^2))
final answer is \[8x^3y^5\sqrt{2x}\]
Thank you satellite 73, tremendously helpful!!
yw (easy when you see what to do right? works with any radical)
