A school is building a rectangular stage for its chorus. The stage must have a width of 6 feet. The area of the stage must be at least 30 square feet. (The stage must hold all the singers.) Write an inequality that describes the possible lengths (in feet) of the stage. Use for the length of the rectangular stage.

answer: 25 is the correct answer

step-by-step explanation:

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)
