A camp needs 100 students to help with the 4-year campers. Eight students from 4 different classes have agreed to help. How many more students are need? Write an equation that can be used to solve the problem. Then solve the problem . Show your work

x = Students

100=8(4)+x

Equation:

100=32+x

-32   -32

68=x

68 students are needed

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)
