Write the polynomial in standard form.
–7x^2 – x^3 + x^ 5 + 2
a. x^5 + x^3 + 7x^2 + 2
b. x^5 – x^3 – 7x^2 + 2
c. –7x^2 – x^3 + x^5 + 2
d. 7x^2 + x^3 + x^5 + 2

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)
