Which polynomials, given in square inches, could represent the area of a square with whole number side lengths if x is a whole number greater than 2? remember, the formula for the area of a square is a = s2. check all that apply.

~ x2 − 9
~x2 −100
~x2 − 4x + 4
~x2 + 10x + 25
~x2 + 15x + 36

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)
