Question 189879
<font face="Garamond" size="+2">



A fractional exponent means raise the number to the power of the numerator and take the root indicated by the denominator.  Here, you can either square -64 and take the cube root of the result, or you can take the cube root of -64 and square the result.  The order doesn't matter except that the second way is computationally easier if you are doing it in your head.  I did it in my head and got 16.  Check it out on the calculator.
