Rainbow [258]

Please select the best answer from the choices provided
Elena L [17]

<u>Answer:</u>

The correct answer option is d. 9.

<u>Step-by-step explanation:</u>

We are given an expression 27^{\frac{2}{3} } and we are supposed to simplify it.

We can also write 27^{\frac{2}{3} } as (3^3)^{\frac{2}{3} }.

We know the power rule (a^m)^n=a^{mn} which means that to raise a power to a power you need to multiply the exponents.

So multiplying the exponents to get:

(3^3)^{\frac{2}{3} }\\3^{3.\frac{2}{3}

3 gets cancelled by 3 so we are left with:

3^2 =9

Therefore, the correct answer option is d. 9.
