If you want to square something without a calculator you must take the # and estimate between which whole # the square root would be between. The two numbers it is between and multiply them by there selves (like 3 times 3 and 7 times 7, not 3 times 7). What ever the sums of those two numbers you subtract(9 and 49 which you subtract equaling 40). Then you divide the # by 100 equaling 2.5 which you multiply by the time 9 (which you saw in parentheses earlier), then with that sum you divide by 100. Then add that to three (which was your estimate. If the number is very long and complicated just round it to a whole #.

3 and 7 are just examples. Normally, both numbers would be right before and after the #. Like 5 and 7. If the number is a decimal like 3.45 your numbers would be 3 and 4. I am only 12 years old and I invented this as a simple way to solve square rooting technique!

The square root of 16,000,000 is 4,000. This is because the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, 4,000 multiplied by 4,000 equals 16,000,000. The square root is denoted by the symbol √.

square root of 125= 25 times 5 under the radical (25 has a square root so you can take that out of the radical)= 5 times the square root of 5 (Thats your final answer with no calculator)

To find the square root of a number on a calculator, you typically press the square root symbol (√) key followed by the number you want to find the square root of. Some calculators may require you to enter the number first and then press the square root key. The calculator will then display the square root of the number you entered.

To find the square root on a calculator without a radical symbol, you can use the power function. Simply raise the number to the power of 0.5 to find the square root. For example, to find the square root of 16, you can input 16^0.5 into your calculator to get the result.
