There are 32 students in Mr. Morgan's math class. One student will be randomly selected to present their project. If there are 20 boys and 12 girls in the class, what is the probability that the presenter will be a boy?
(Write the answer as a fraction in lowest terms),

Step-by-step explanation:

di fff

6/4

Step-by-step explanation:

or six forths (i belive)

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)
