## How do you calculate square root?

Example: Calculate the square root of 10 ( ) to 2 decimal places.

- Find the two perfect square numbers it lies between. Solution: 3
^{2}= 9 and 4^{2}= 16, so lies between 3 and 4. - Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)
- Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.

## How do you solve root equations?

## What is a square root of 144?

The value of the square root of 144 is equal to 12. In radical form, it is denoted as √ 144 = 12.

## IS 400 a perfect square?

400 is a perfect square. Because 20 * 20 = 400.

## Why is 9 The square root of 81?

Explanation: 81 = 9 ⋅ 9 then the square root of √ 81 = 9. Because the double multiplication for the same sign is always positive, the square root is also valid with the other sign 81 =(− 9 )⋅(− 9 ) then √ 81 =− 9 and we can say that √ 81 =± 9.

## How can I get root 3 value?

It is not a natural number but a fraction. The square root of 3 is denoted by √ 3. The square root basically, gives a value which, when multiplied by itself gives the original number. Hence, it is the root of the original number. Table of Square Root.
