Idon’t know how to simplify radical expressions

FIrst you want to find the largest perfect square. Next, you want to rewrite the radical number then rewrite the radical number idk how to explain it so i will show you an example:

the square root of 8= the square root of four and the square root of two.

Then simplify:

So it would be 8= 2 square root of 2.

Hope this helps, have a good day. c;

Here are some examples:-

√8 = √(4*2)  Note we picked 4 as a factor because its a perfect square

√(4*2) = √4 *√2

= 2√2

√63 = √(9*7)

= 3√7

answer: 177/8
