Zoe bought a $25 sweatshirt on sale at a 30% discount. she wrote the expression 25−0.3(25)25−0.3(25) to find the discounted price of the sweatshirt.

which equivalent expression could she also use to find the discounted price?
1.3(25)

(1 + 0.3)25

(1−0.3)25(1−0.3)25

25 + 0.3(25)

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)
