Question

Simplify the radical .

9d2
81d3
9d3
9d6

Answer 1

Given:

Consider the given radical expression is:

`√(81x^6)`

To find:

The simplified form of the given expression.

Solution:

We have,

`√(81x^6)`

It can be written as:

`√(81x^6)=√(9^2(x^3)^2)`

`√(81x^6)=√((9x^3)^2)`
`[\because (ab)^n=a^nb^n]`

`√(81x^6)=9x^3`

Therefore, the correct option is C.
