Look at the figures below. The area of the larger rectangle is 4 times the area of the smaller rectangle. Fill in the missing measurement. 16.2 cm 12.5 cm 25 cm​

answer: i forgot

step-by-step explanation:

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)

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
