5) A student earned grades of C, A, B, and A. Those courses had these corresponding numbers of credit hours: 3, 6, 2, and 6. The grading system assigns quality points to letter grades as follows:
A= 4, B = 3, C= 2, D=1, and F= 0. Compute the grade point average (GPA) and round the result
to two decimal places.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
