Answer 2

First we will find all factors under the cube root: 686 has the cube factor of 49.

Let's check this width ∛49*2=∛686. As you can see the radicals are not in their simplest form.

Now extract and take out the cube root ∛49 * ∛2. Cube of ∛49=7 which results into 7∛2

All radicals are now simplified. The radicand no longer has any cube factors.

³ √686= 8.81944734926
