-2= 5x+ 3? what is the answer help

x=-1

Step-by-step explanation:

5x+3=-2

subtract 3 from both sides

5x=-2-3

Subtract 3 from -2 to get -5

5x=-5

Divide by 5 on both sides

x=-5/5

Divide -5 by 5 to get -1

x=-1

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)
