What is 1000 words in 5 minutes rate as a unit rate.

200 words per minute

Step-by-step explanation:

1000:5

1000/5 reduced will give you your unit rate.

200 words/minute

If 1000 words were read in 5 minutes, each minute would be 1000 divided by 5 which is 200.

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)
