There is, however, this is just a approximation.
Solve for the variables that follow, where N(squared) is the closest perfect square to S. The directions follow:
d = S - N2
P = d (over) 2N
Answer = N + P
Let's try finding the square root of 79.
d = 79 - 92
So d = -2
P = -2 (over) 2(9)
So P = -0.1 (repeating)
Answer = 9 + -0.1 (repeating)
The square root of 79 about equals 8.8 (repeating)
And since 8.8 (repeating) = 8 and 8 (over) 9, we can calculate that 8.8 (repeating) squared equals about 79.01234567...
It is really accurate, so good luck using this approximation!

What does it mean to find the square root of a number?
It means you are finding what number multiplied by itself will give you the number you are finding the square root of.
What is the square root formula?
The formula of square root is basic once you learn it. To figure out the square root of a number you must know what a square number is. A square number is the product of a multiplication problem such as 7x7, 123x123 and 14x14. So the square root of 7 is 49. A trick to figuring out the square root of a number is adding consecutive odd number to the previous problem.
