What is the first step in simplifying the division of 14 by 7 using cube roots?

• Divide 14 by 7

• Multiply by 7

• Find the cube root of 14

• Divide by 2

Why can't you take the cube root of X squared directly?

• Because X squared is already simplified

• Because X squared is negative

• Because X squared is too large

• Because X squared is not a perfect cube

To what power must X be raised to allow for cube root simplification?

• Fifth

• Fourth

• Third

• Second

What do you multiply by to simplify the expression involving cube roots of X and Y?

• Cube root of 2

• Cube root of XY squared

• Cube root of X squared

• Cube root of Y

What is the final simplified expression of the problem?

• Cube root of 14 over 7

• Cube root of 2 times X times Y squared over X Y

• Cube root of X cubed Y cubed

• Cube root of 2 over X squared Y
