Sebastian is taking a multiple choice test. His grade is given by the equation y = 45 – 3x, where y represents his final score and I represents the number of questions he got wrong. What could the number 45 represent in the equation? O The points he loses for every wrong question. The score he would get if he only missed one question. The number of problems on the test. His score with o problems wrong. Submit Answer​

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)
