1. Which equation is graphed in the figure?
A. – 3x – 4y - 8=0
B. -3x + 4y + 8 = 0
OC. 3x + 4y - 8 = 0
D. 3x - 4y - 8 = 0

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)

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
