6) 60% of an audience at a theatre production are over the age of 60. Write down the ratio of people under the age of 60 to the people over the age of 60. Write your
answer in the form 1: n

60%

=60/100

=6/10

=3/5

=3:5

it 2

step-by-step explanation:

8^1/3=2

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)
