Which expression represents a factorization of 3q - 5qr + 4pq ? A.1/3 q(1 - 15r + 12p)
B.1/2 (1.5q - 2.5r + 2p)
C. 1/4 q(12 - 20r + 16p)
D. 1/6 q(2q - 0.8r + 24p)

1) Find the Greatest Common Factor (GCF).

GCF = q

2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

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)
