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.

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.”
