Rewrite the expression with a rational exponent as a radical expression.

Rewriting the expression with a rational exponent as a radical expression we get

Step-by-step explanation:

We need to rewrite the expression with a rational exponent as a radical expression.

The expression given is:

First we will simply the expression using exponent rule

As we know 2 and 18 are both divisible by 2, we can write

Now we know that

Using this we get

So, rewriting the expression with a rational exponent as a radical expression we get
