Triangles ABC and PQR are given. ABC = PQR by SAS. If m m AB = 5y-7,
and PQ = 3y - 1,
then which of the following statements are true? Select all that apply.

A) AB=8
B) m C) y=1
D) x is seven units greater than y.
E) M F) PQ= 3

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)
