Simplify the expression.
Sati [7]

Answer:

LAST OPTION: x^9

Step-by-step explanation:

For this exercise it is important to remember the Power of a power property, which states that:

(a^m)^n=a^{mn}

The expression given in the exercise is:

(x^\frac{3}{2})^6

Therefore, in order to simplify it, you  must apply the Power of a power property explained before.

Then, you get the following expression:

=x^{(\frac{3}{2}*6)}=x^{(\frac{3*6}{2})}=x^{\frac{18}{2}}=x^9

As you can notice, the expression obtained matches with the expression provided in the last option.
