Monica found the volume of the prism below using the expression 4 + (4 times one-half).

What errors did Monica make? Check all that apply.

She should have counted only 2 unit cubes instead of 4.
She should have counted 8 one-third cubes instead of only 4.
She should have found the total value of the one-third cubes by multiplying by One-third instead of by One-half.
Each fractional cube is worth Two-thirds instead of the One-half that she used.
She cannot stack more than one layer of fractional cubes in a prism.

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)

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
