call the square, y. A square root of a number is the number, say x, so that
x^2=y (or x squared=y)
finding the square root of a perfect square is easy to find.
for example: sqrt(9)=3, and 3*3=9
for numbers that are not perfect squares is harder.
You can simplify what is in the square root sign, making it so you have a perfect square as one of the numbers. Then take out the perfect square , and put its square root outside the square root. For example,
sqrt(162)=sqrt(81*2)=9sqrt(2)
That is pretty crazy!
it would be better to search on the Internet, or ask Mr. Hui
