Examplea
find the surface area of the rectangular prism.
6
m
8 m
3 m

180 m²

Step-by-step explanation:

Surface area = 2 ( lw + wh + lh)

                     = 2( 6x3 + 3x8+8x6)

                      = 180 m²

3, nah jk it's 2

step-by-step explanation:

it is 3 cause i'm sanic

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)
