The expression 1.08s + 1.02b1.08s+1.02b1, point, 08, s, plus, 1, point, 02, b predicts the end-of-year value of a financial portfolio where sss is the value of stocks and bbb is the value of bonds in the portfolio at the beginning of the year. What is the predicted end-of-year value of a portfolio that begins the year with \$200$200dollar sign, 200 in stocks and \$100$100dollar sign, 100 in bonds? I need help on this 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)
