We have 4 ways to use inverse operations to solve for x
a. is wrong because we need to take a square root of both sides not divide both sides by 2
b. is wrong because we need to take a square on both sides not to take the square root of both sides
c. is right we need to cube both sides
d. is wrong because we need to take a cube root of both sides not subtract 3 from both sides
As we can see C is the right answer.
