Find the principal (positive) square root of 10. if necessary, round the answer
to the nearest hundredth (two decimal places).

3.16

Step-by-step explanation:

The non-rounded answer is 3.16227766017, but to round it, you look to the place after the first six, which is a two, so it doesn't change the number before (6).

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)
