Choose the equations in which n=100 will make the equation true.

1:12.4 divided by n=0.124

2:3.8 divided by n=0.038

3:52350divided by n=52.35

4:850.4 divided by n =85.04

5:0.41 divided by n =0.0041

Step-by-step explanation: Move the decimal two times to the left if you divide by 100.

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)
