You are given functions f and g such that f(n)=o(g( is f(n)∗log2(f(n)c) = o(g(n)∗log2(g( ? (here c is some constant > 0. you can assume that f and g are always bigger than 1.. a) true. b)false. c)depends on c. d) depends on f and g

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)
