Cube roots 2

The  exercise appears under the Pre-algebra Math Mission. This exercise is similar to the simplify square root problems and manipulative.

Types of Problems
There is one type of problem in this exercise:


 * 1) Simplify the cube root: This problem provides a number and the student is asked to find the cube root. The manipulative requires the student to put the number that escapes on the outside of the radical and the one that remains on the inside of the radical.Cr2-1.png

Strategies
Ability and proficiency with radicals and rapid prime factorization would ensure success on this exercise.
 * 1) If the number is broken into it's prime factorization, then "triplets" will escape from the radical and other numbers will remain.
 * 2) Numbers that meet on the outside will be multiplied, as will numbers that remain on the inside.

Real-life Applications

 * 1) Radicals, in particular the cube root, is used to undo integer exponents.
 * 2) Cube roots occur in undoing volume calculations.
