## How do you calculate square root?

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

1. Find the two perfect square numbers it lies between. Solution: 32 = 9 and 42 = 16, so lies between 3 and 4.
2. Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)
3. Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.

## 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.

## Is 9 a perfect square?

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

## Is √ 9 a rational or irrational number?

√9 = 3 which is a natural number, that is can be expressed in the form a/b where a and b are both integers. 9 is a perfect square (square of an integer). In general, square root of a non-perfect integer would be irrational. Answer is no, because root9 result is 3 which is not in rational form.

## Is square root of 9 a whole number?

The square root of 9 is a whole number. The square root of 9 is 3.

## What is the value of root 9 Root 4?

√ is called the radical symbol or radix and in this example, the principal square root of 4 is 2 which is denoted by √ 4 = 2 because 22 = 2 • 2 = 4 and 2 are non-negative. The number underneath the radical symbol is called the radicand. Square Root From 1 to 50.
