In this example, we are using the product rule of radicals in reverse
to help us simplify the cube root of
When you simplify a radical, you want to take out as much as possible.
The factor of
that we can take the square root of is
. We can write
and then use the product rule of radicals to separate the two numbers.
We can take the square root of
we will have to leave the rest of it under the square root.
