37. a group of people share equally in a $20,000,000 lottery. before
the money is divided, two more winning ticket holders are
declared. as a result, each person's share is reduced by $500,000.
how many people were in the original group of winners?

20 people

Step-by-step explanation:

You do 20,000,000 divided by 2 in a calculator, which is 10,000,000 then divide it by 500,000 to get 20

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)
