How do i solve this i am very confused

Step-by-step explanation: Factor the polynomial: -2x3 - 4x2 - 6x

A. -2x(x2 + 2x+3)

B. -2x{-x2 - 2x - 3)

C. 2x(x2 + 2x+3)

D. -2x(-x2 - 4x - 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)
