Mason used distributive property of multiplication to help him solve the equation 3 x 9 = . Mason did not get the same answer for each side of the expression. Explain the steps required to correct his mistake. 3 x 7 = (3 x 3) + (3 x 6)
21 = 9 + 18
21 = 27 (4 points)

its the fourth option

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)
