Finite math-summer b 2019 (1) quiz: quiz 4 this question: 1 pt two statements are considered to be equivalent if: o a. they have the same number of columns in their truth tables. o b. they have the same number of t's and f's in the final column of their truth tables. o c. the final columns of their truth tables are the same. o d. they have the same symbols (not necessarily in the same order) in their statements.

the answer is b

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)
