Question

Which expression is equivalent to128x5y82x7y55 ? Assume x > 0 and y> 0HE888.+/X

Answer 1

we have the expression

`\sqrt[]{(128x^5y^6)/(2x^7y^5)}`

simplify

we have that

128/2=64=2^6

(x^5y^6)/(x^7y^5)=y/x^2

substitute in the original expression

`\sqrt[]{\frac{2^6y}{x^2^{}}}=(2^3)/(x)\sqrt[]{y}=(8)/(x)\sqrt[]{y}`
