You can either use logarithmic tables, or trial and error.
With trial and error, you make a guess at what the square root might be, and then see how close you are to the number when you multiply the guess by itself.... say I'm looking for the square root of 12,345. I know that it must be more than 100 - because 100 x 100 = 10,000 so I can guess at 120 and see what 120 x 120 makes.
That turns out to be 14,400 - which is a bit high, so I can try halfway - 110 x 110 = 12,100.... so now I'm getting closer.
I can try like this to refine the number closer and closer to the desired number. 111 x 111 = 12,321... so I need to go to decimal places....
111.5 x 111.5 = 12432.25... still a but high, so I'll drop down to
111.2 x 111.2 That gives me 12365.44... so I need to go down more
111.1 x 111.1 = 12343.21 - now I'm getting really close.
Let's try 111.13 x 111.13... and so on, getting closer and closer all the time.

When a squared plus b squared equals c squared what is the square root of the square root of the square root of a squared squared squared plus b squared squared squared?
Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
