Adepartment store is advertising men’s clothing dress pants at 25% off the original price if your original price is $82 what is the sales price of the dress pants?

$61.50

Step-by-step explanation:

You do 82*.25

Then you get 20.5

Then you do 82-20.5

Lastly you get 61.5

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)
