using n to represent the number.
n^2 when squared rooted equals the original number, n; and when a number squared rooted is squared, it also equals to the original number.
Hence the relationship is, when either of the operations is applied to the opposite operation (i.e. n^2 is opposite to square root of n) is result is always the original number, n.

Yes, the whole idea of taking the "square root" of a number is, for example for the square root of 2, to find the number that, when squared, gives you 2. if you try to do both, they cancel each other out.
they cancel each other out. the square root of 5 raised to the second power = 5
put it in a calculator. square root means what two numbers that are exactly the same that are multiplied by each other. 8.94427191 * 8.94427191 = 80
The square-root and the square cancle each other out so you will only be left with the number Example: √2² Would become 2
When you have calculated the square root of each number, simply add the results together and you will have the answer.
