Multiplying Radical Expressions

We can multiply radicals provided they have the same index. To multiply the radicals, we multiply their radicands. The resulting radical has the common index.

For example, let’s find this product:
We multiply the radicands.
Finally, we simplify. = 2
If the expressions being multiplied contain factors that are not under a radical symbol, multiply those factors. Then multiply the radicands of radicals that have the same index.
For example, let’s find this product:
Multiply 8w by 5y. Multiply 7y by 4x.
In the following multiplication problem, we use the Distributive Property to remove the parentheses.
Find this product:
Distribute to each term inside the parentheses.


Example 1

Multiply and simplify:

Factor each radicand. Use perfect square factors when possible.
Write each radical as a product of radicals. Place each perfect square under its own radical symbol.
Simplify each radical.
