To square a number means to multiply it by itself. For example, the square of 4 is 16. We could say that four squared is 16. We could also write that as 4² = 16.
The little 2 is called an exponent. It doesn't mean to multiply 4 times 2, It means to multiply 4 times itself, in this case, giving us 16.
A few more examples are 4² = 16, 9² = 81, and 53² = 2809. Notice how quickly the results of squaring become very large.
We refer to numbers like 16 and 81 as perfect squares, simply because they are the result of having squared a number
Reverse the process to finf the root.
I like the square root of 69, since it come out as eight something ;)

HI TO FIND THE SQ ROOT OF A NUMBER IS THE OPPOSITE OF THE SQ OF A NUMBER IE:
100 THE SQ ROOT IS 10 THE SQ ROOT OF A NUMBER IS A NUMBER WHICH MULTIPLYED BY ITSELF GIVES YOU THE ORIGINAL NUMBER
EXAMPLES 9 SQ ROOT = 3 AS 3 X 3 = 9 49 SQ ROOT = 7 AS 7 X 7 =49
THESE ARE EASY EXAMPLES FOR MORE COMPLICATED NO'S YOU WILL NEED A CALCULATOR OR MATHS TABLES BOOK
HOPE THIS HELPS
