The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4.

The square root of a number can be positive or negative, depending on the number itself. For example, the square root of 4 is 2, but the square root of -4 is also 2, because (-2) x (-2) = 4.

The square root of a number can also be written as a radical symbol, with the number written underneath. For example, the square root of 4 can be written as √4, which is equal to 2.

In general, the square root of a number can be found using a calculator or by hand using a method called “long division.” It is also possible to estimate the square root of a number by finding the square root of a number that is close to it and using that as a starting point. For example, to find the square root of 4, you might start by finding the square root of 5, which is approximately 2.236, and then adjusting this estimate until you get as close as possible to the actual square root of 4.
