Question

Which expression is equivalent to 3 square root 27x^18? 3x^3 3x^6 9x^3 9x^6

Answer 1

3 x^6

Explanation:

I believe you are asking for the cube root of (27x^18)

(27 x^18) ^ (1/3)

I will use the property (ab)^c = a^c * b^c

27 ^ 1/3 * x^18 ^ 1/3

Now I can use the property a^ b^ c = a^ (b*c)

3 * x^( 18* 1/3)

3 * x^ (6)

3 x^6
