Question

Pl help it’s for a grade

Answer 1

Explanation:

Given,

1. The given expression is
`\sqrt[10]{x^9}`.

We need to write it into exponential form.

We know that,

`\sqrt[a]{x} =x^(1/a)`

Here, a = 10

So,

`\sqrt[10]{x^9}=(x^9)^(1/10)\\\\=x^{9* (1)/(10)}\\\\=x^(9/10)\\\\=x^(0.1)`

2.

`(\sqrt[4]{3y} )^3\\\\=((3y)^3)^(1/4)\\\\=3^{3* (1)/(4)}* y^{3* (1)/(4)}\\\\=3^(3/4)y^(3/4)`

Hence, this is the required solution.
