Question

Simplify the radical . 9d2 81d3 9d3 9d6

Answer 1

Given:

Consider the given radical expression is:

$\sqrt{81x^6}$

To find:

The simplified form of the given expression.

Solution:

We have,

$\sqrt{81x^6}$

It can be written as:

$\sqrt{81x^6}=\sqrt{9^2(x^3)^2}$

$\sqrt{81x^6}=\sqrt{(9x^3)^2}$            $[\because (ab)^n=a^nb^n]$

$\sqrt{81x^6}=9x^3$

Therefore, the correct option is C.
