What does square root mean

thanks ms. Sue.

We square a number by multiplying the number by itself.

2^2 = 2 * 2 = 4 The square root of 4 = 2
3^2 = 3 * 3 = 9 The square root of 9 = 3
4^2 = 4 * 4 = 16 The square root of 16 = 4

You are welcome.

The square root of a number is a value that, when multiplied by itself, gives the original number. In other words, it is the reverse function of squaring a number. For example, the square root of 25 is 5 because 5 multiplied by itself (5 x 5) equals 25.

To find the square root of a number, you can use a calculator or a mathematical method called "estimation" if you don't have a calculator.

If you have a calculator:
1. Enter the number for which you want to find the square root.
2. Look for the button labeled "sqrt" or "√" on your calculator.
3. Press that button and the calculator will display the square root of the number.

If you don't have a calculator, there are several estimation methods you can use, such as the "guess and check" method or the "divide and average" method.

Using the guess and check method:
1. Start by guessing a number that might be close to the square root of the given number.
2. Square the guess and compare it to the original number.
3. Adjust your guess according to whether the result is too high or too low.
4. Repeat steps 2 and 3 until you have a close approximation of the square root.

Using the divide and average method:
1. Start by dividing the given number by 2.
2. Take the average of the result and the original number divided by the result.
3. Repeat step 2 until you have a close approximation of the square root.

Both methods can be repeated multiple times to get a more accurate answer.
