• They are essential for solving addition problems.

• They are used in division calculations.

• They simplify the process of finding square roots.

What is the first step in the long method for finding the cube root of X to the 8th power?

• Add 8 to X.

• Divide X by 8.

• Subtract 8 from X.

• Multiply X by itself 8 times.

In the long method, what do you do after breaking down X to the 8th power?

• Take the square root of each part.

• Add all the parts together.

• Multiply each part by 2.

• Take the cube root of each group of three X's.
