The number of necklaces Lilly can make varies directly with the amount of time she spends making the necklaces. She can make 6 necklaces in 25hour. How many necklaces can Lilly make in 5 hours?

20.8333333 (20)

Step-by-step explanation:

You need to find how many in each hour to you do 25 divided by 6. And then you multiply your answer by 5 and you get 20.8333333. Or 20.

Hope I helped :(

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)
