Question

Ayna and Leslie both simplified the expression. Which student is correct

Answer 1

Given:

`\sqrt[]{18x^4y^5}`

The expansion is,

`\sqrt[]{18x^4y^5}=\sqrt[]{2*3*3* x* x* x* x* y* y* y* y* y}`

On simplification we get,

`\begin{gathered} =\sqrt[]{2*3^2* x^2* x^2* y^2* y^2* y} \\ =3x^2y^2\sqrt[]{2y} \end{gathered}`

Hence, Leslie was correct.
