Step by step simplification process to get square roots radical form:
First we will find all factors under the square root: 2516 has the square factor of 4.
Let's check this width √4*629=√2516. As you can see the radicals are not in their simplest form.
Now extract and take out the square root √4 * √629. Root of √4=2 which results into 2√629
All radicals are now simplified. The radicand no longer has any square factors.
The square root of two thousand, five hundred and sixteen √2516 = 50.1597448159
Which Is not one of your choices.
