If 5(x-4)+2= -173 what is the value of x?

38.2

Step-by-step explanation:

5 (x-4) + 2 = 173

=> 5x - 20 + 2 = 173

=> 5x - 18 = 173

=> 5x - 18 + 18 = 173 + 18

=> 5x = 191

=> 5x/5 = 191/5

=> x = 38.2

So, x is 38.2

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)

i think the correct option is the second option.
