The calculator will display the product of the two cube roots and explain how it was derived.

The Formula Explained

When multiplying two cube roots with variables, the formula is:

∛(a) × ∛(b) = ∛(a × b)

This formula shows that the product of two cube roots is equal to the cube root of the product of the radicands (the expressions inside the cube roots).

For example, if you have ∛(2x) × ∛(3y), the product would be ∛(2x × 3y) = ∛(6xy).

Note: This formula assumes that the radicands are positive real numbers. Complex numbers or negative radicands require additional consideration.

Worked Examples

Example 1: Simple Variables

Calculate ∛(3x) × ∛(4y).

Using the formula:

∛(3x) × ∛(4y) = ∛(3x × 4y) = ∛(12xy)

The product is ∛(12xy).

Example 2: Variables with Exponents

Calculate ∛(5a²) × ∛(2b³).

Using the formula:

∛(5a²) × ∛(2b³) = ∛(5a² × 2b³) = ∛(10a²b³)

The product is ∛(10a²b³).

Example 3: Mixed Coefficients and Variables

Calculate 2∛(6c) × 3∛(8d).

First, separate the coefficients and the cube roots:

2∛(6c) × 3∛(8d) = (2 × 3) × ∛(6c × 8d) = 6 × ∛(48cd)

The product is 6∛(48cd).

Frequently Asked Questions

What is the formula for multiplying cube roots with variables?: The formula is ∛(a) × ∛(b) = ∛(a × b). This means you multiply the expressions inside the cube roots and take the cube root of the result.
Can I multiply cube roots with different variables?: Yes, you can multiply cube roots with different variables. The variables are combined in the radicand, and their exponents are added if they are the same variable.
What if the cube roots have coefficients?: If the cube roots have coefficients, multiply the coefficients separately from the radicands. For example, 2∛(3x) × 4∛(5y) = (2 × 4) × ∛(3x × 5y) = 8∛(15xy).
Are there any restrictions on the variables in the cube roots?: The variables must be real numbers, and the radicands must be positive. Complex numbers or negative radicands require additional mathematical consideration.
How do I simplify the result of multiplying cube roots?: To simplify, factor the radicand and look for perfect cubes. For example, ∛(27x³) can be simplified to 3x because 27 is a perfect cube and x³ is (x)³.
