What are the answers to this!?!? Just put like “A = False” but the right answers A. 8.35 + 7.9 = 16.25

B. 5.31 - 3 = 2.31

C. 94.43 + 74.9 = 169.33

D. 183.7 + 28.34 = 467.1

D. 183.7 + 28.34 = 467.1

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)
