Reagan knits 3 centimeters of a scarf each night. How many nights will Reagan have to spend knitting in order to knit a total of 6 centimeters of the scarf?

2 Nights

Step-by-step explanation:

If Reagan knits 3 centimeters of a scarf each night then all you would have to do is take 6 divided by 3 which would equal 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)
