Which expression is equivalent to
8g + 2+ 4g - 2 -2g?
1. 16g+4
2.16g
3.10g+4
4.10g

4. 10g

Step-by-step explanation:

8g + 2 + 4g - 2 - 2g

8g + 2 + 4g - 2 - 2g = 10g

8g + 2 + 4g - 2 -2g = 0

Final

10g

i think the answer is b)

step-by-step explanation:

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)
