Question

What is square root number

Answer 1

Here's an example

9 = 3 * 3 So we say 3 is the square root of 9. Its the number which when multiplied by itself gives 9. 9 is the square of 3.

Also 4 is the square root of 16 because 4 * 4 = 16. Also -4 is a square root of 16 because -4 * -4 = 16.

The symbol used for square root is √. (√16 = 4).

Most whole numbers do not have a square root which is a whole number for example try finding the square root of 10 on your calculator . Mine gives me

3.16227766. Actually this is an irrational number ( it goes on without bound)s.

In the UK we call √10 a surd . In the USA its called a radical.

Answer 2

The square root of a number would be the inverse of an exponent.

so let’s say you have 9 to the 2nd power, or 9^2, it would be 81, because 9 multiplied by itself 2 times (hence the exponent, second power) would be 81.

now, the square root of 9 would be the number that, multiplied by itself 2 times, would be equal to 9.

3 times 3 is equal to 9, and since 3 is being multiplied by itself two times to get 9, the square root of 9 is 3.

does this make sense now?
