what math class are you in? because there is a very specific way of doing it if you are looking for the square root of a non-perfect square or imaginary number such as 4+7i or -11

Oops that was supposed to be an answer not a comment

ok then u probably don't need to know the complicated method but it involves using the real number axis and the imaginary axis to find the coordinates as a function in the form of r+? where r is the radius of the resultant vector and ? is the angle formed from the real number axis

Why can't you use one? That's bull.
They let you use one on the SATs so, your school should blow up.

The square root is the number that when multiplied by itself it makes a product. For example the square root of 4 is 2 because 2 times 2 is 4. Hope this helps.

What number times itself is the answer. Square root of 9 is three because 3 times 3 is 9. Calculators help too :)

Example: 5 is the square root of 25. Why? Because 5 times itself is 25. Any number times itself equals a square. So to find a square root just find the root number.
I hated this unit too. I hope this helped a bit! (Btw we weren't allowed calculators either so I can sympathize!)
