How do you multiply cube roots?

Back

To multiply cube roots, you can multiply the numbers inside the roots and then take the cube root of the result: @@ oot[3]{a} imes oot[3]{b} = oot[3]{a imes b}@@.

Front

What is the simplified form of @@ oot[3]{54} imes 2 oot[3]{4}@@?

Back

The simplified form is 12.

Front

What is the sum of @@ oot{5} + oot{20}@@?

Back

The sum simplifies to @@3 oot{5}@@.

Front

How do you subtract cube roots?

Back

To subtract cube roots, you can subtract the coefficients of like terms: @@ oot[3]{a} - oot[3]{a} = (c - d) oot[3]{a}@@.

Front

What is the result of @@8 oot[3]{11} - 5 oot[3]{11}@@?

Back

The result is @@3 oot[3]{11}@@.

Front

What is the product of @@ oot{3} imes oot{15}@@?

Back

The product simplifies to @@3 oot{5}@@.

Front

How do you divide cube roots?

Back

To divide cube roots, you can divide the numbers inside the roots and then take the cube root of the result: @@rac{ oot[3]{a}}{ oot[3]{b}} = oot[3]{rac{a}{b}}@@.

Front

What is the simplified form of @@rac{ oot[3]{108}}{ oot[3]{500}}@@?

Back

Front

What is the square root of a number?

Back
