What is a square root of a whole number. To multiply radicands multiply the. The Multiplication Property of Square Roots The key to learning how to multiply radicals is understanding the multiplication property of square roots.

If thereare any coefficients in front of the radical sign multiply them together as well. How do you multiply two squares together. If you can then simplify.

In this regard can you multiply two roots. 2 and 3 6. So we want to rewrite these powers both with a root with a denominator of 6.

A slightly more complex example Step 1. When you multiply a whole number by a square root you just put the two together with the whole number in front of the square root. To multiply radicals you can use the productproperty of square roots to multiply the contents ofeach radical together.
