Answer:

8i

Step-by-step explanation:

<em>When a quantity is raised to a fractional power, you need to root it to the power of the denominator. </em>

<em>For example, </em><em>(-64)^(1/2)  =  √(-64) </em>

<em>Since you are taking the root of a negative, you will need to put an </em><em>i</em><em> (imaginary) in your answer.</em>
