Which statement is true of triangles p and q? a. they are similar because their corresponding angles have proportional measures and their corresponding sides are congruent. b. they are not similar because their corresponding angles are congruent. c. they are similar because their corresponding angles are congruent and their corresponding side lengths are proportional. d. they are not similar because their corresponding side lengths are not proportional.

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)
