There is a method , based on the binomial series, that my Dad learned in school and which he taught me in an hour or so when I was in fifth grade, to find square roots. It is easy enough to be useful but takes a little while to learn to do quickly, so few if any grade school teachers learn it . The say use a calculator and apparently their supervisors agree. (sad, I think),.
I do find a web page that I have added as a related link just below. I hope you can find and follow what it says.

How do you know whether a number is a perfect square?
A number is a perfect square when you can directly extract its square root in whole numbers and without approximation. When you subject a certain number to a radical sign, you can extract its square. Example: 25 is a perfect square. it's square root is 5, since 5 x 5 is equal to 25
How can a make a batch file to know if a number is not a perfect square?

What is square root of a number?
The square root is the number which is times by itself, to get the square number.
How do you square root in my maths?
the square root of a number is the number that is multiplied by itself to get that number, for example the square root of 9 is 3
What is the square root of a negative number plus the square root of a negative number?
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)

Is the square root of a positive number an irrational number?
Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).
What is the difference between a square root and a square number?
3 is the square root of 9. 9 is a square number. 9 is the square root of 81. 81 is a square number.

What is the square root of a square that has no root?
It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
What is the square root of the number 9?
The number 3 is the square root of the number 9 !
Is the square root of 25 a rational number?
The square root of 25 is 5 ... rational.
Is the square root of fifty a natural number?
No - a natural number is a whole number. Therefore, the square root of 49 is a natural number, but the square root of 50 is not.
What is the square root of 51?
The square root of 51 is an irrational number and it is about 7.14128429
