Usually via an iterative solution that calculates the square of a value and correcting it until a close enough answer is found. This is called successive approximation.
Another method that might be used and gives an exact answer if carried out far enough is similar to long division in operation (but I don't think any calculators actually use this).

The same way you find the square root of any number. The fastest way would be to type 225, followed by the square root key, in a calculator.
Use a calculator. Most will allow you to find 70(1/4) Or find the square root of the square root of 70.
The square root of 0.375 is approximately 0.612. To find the square root of a decimal number, you can use a calculator or long division method. In this case, you would take the square root of 375 (which is 19.364) and then divide by 10 to get the final answer of approximately 0.612.
Taking the square root of an atomic number is not particularly useful. Anyway, you can look up the atomic number in a periodic table or some other reference material (searching Wikipedia for "manganese" should work well), and then use a calculator to take the square root.
Use a calculator. Schools no longer teach the by-hand method of determining square roots (that's differential calculus, don't worry about it).
