Irene has a budget for school stationery of $$$49, but has already spent $$$14.66 on books and folders. Let $$p represent the amount that Irene can spend on other stationery. Write an inequality that shows how much she can spend on other stationery, and solve for $$p. 30 points

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)

good luck on your studies! : )
