First we will find all factors under the square root: 147 has the square factor of 49.Let's check this width √49*3=√147. As you can see the radicals are not in their simplest form.Now extract and take out the square root √49 * √3. Root of √49=7 which results into 7√3All radicals are now simplified. The radicand no longer has any square factors.

the answer is 
7√3 

hopes thats helps
