Factor and then solve the question.

X^2-6X=7

The solution set is {-1, 7}.

Step-by-step explanation:

X^2-6X=7

X^2 - 6X - 7 = 0

(X - 7)(X + 1) = 0

X = 7, -1.

sorry if this isnt what you're looking for i dont really understand the question

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)
