Could anyone figure this out really quick!!?

Percent of change is 70%.

Step-by-step explanation:

Since we have given that

5/3 to 3/8

We need to find the percent of change.

So, First we find the difference between them:

5/4-3/8=10-3/8

10-3/8=7/8

So, We know the formula for "Percent of change":

difference/original times 100

7/8/5/4 times 100

7*4/5*8*100

70%

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)
