As a square root example if I know the 10,000 ohm resistor has a rating of 0.25 watts I can calculate the maximum worst case voltage that could appear across it, before damage could occur. This is found by taking the resistance value - multiplying the wattage rating - and finding the square root. Square root of 2500 is 50.
How to Calculate a Square Root by Hand. In the days before calculators, students and professors alike had to calculate square roots by hand. Several different methods have evolved for tackling this daunting process, some giving a rough...

Before we learn to calculate it, it’s important to understand what it really means, how we calculate it normally. Quick Intro: Calculating a square root is an inverse calculation for coming back to the root of a square. So, when you calculate the square of 10 by multiplying it with its self, that’s (10 * 10 = 100).

How to find square roots, cube roots, and nth roots in Excel using exponents and functions in formulas. How to find square roots, cube roots, and nth roots in Excel using exponents and functions in formulas. ... Calculate a square root. The syntax for the SQRT() function is: =SQRT(number)
N equals the number whose square root you are trying to find. It goes inside the check mark symbol. Thus, if you are trying to find the square root of 9, you should write a formula that puts the "N" (9) inside the check mark symbol (the "radical") and then present an equal sign and the 3. This means the “square root of 9 equals 3.”
In numerical analysis, a branch of mathematics, there are several square root algorithms or methods of computing the principal square root of a non-negative real number.For the square roots of a negative or complex number, see below.. Finding is the same as solving the equation () = − = for a positive .Therefore, any general numerical root-finding algorithm can be used.
