Question

What is the cube root of ______?

Answer 1

Answer:

3a^4

Step-by-step explanation:

The cube root of an expression breaks the expression into a term which multiplies by itself twice to make the expression. For example, the ∛8 = 2 since 2*2*2 = 8. A cube root looks for factors which form a group of 3 to make the expression. Using this definition and example, find the cube root of 27a^12.

27 breaks into 3*3*3. So the cube root of 27 is 3.

a^12 breaks into (a^4)(a^4)(a^4). So the cube root is a^4.

Together the cube root of 27a^12 is 3a^4.
