Model 3 + ( -4 ) on the numbe line.

I ready, Please HELP

Step-by-step explanation:

Hey, I got u

3+ (-4)=7

Why?

Because () around a negative will sometimes mean absolute value.

Absolute value means positive.

cool?

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

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)
