Question

Expression and assume that X, y, and z denote any positive real numbers

Answer 1

a) given equation is,

`\begin{gathered} \sqrt[8]{x^8y^4z^(4\:)} \\ =\sqrt[8]{x^8}\sqrt[8]{y^4z^4} \\ =x\sqrt[8]{y^4z^4} \end{gathered}`

b) the given equation is

`\begin{gathered} \sqrt[3]{√(64x^6)} \\ =\sqrt[3]{8x^3} \\ =2\sqrt[3]{x^3} \\ =2x \end{gathered}`
