# Python profram to calculate square of a given number

Given a number, the task is to write a Python program to calculate square of the given number.

**Examples:**

Input:4Output:16Input:3Output:9Input:10Output:100

We will provide the number, and we will get the square of that number as output. We have three ways to do so:

- Multiplying the number to get the square
**(N * N)** - Using Exponent Operator
- Using math.pow() Method

**Method 1: Multiplication**

In this approach, we will multiply the number with one another to get the square of the number.

**Example:**

## Python3

`# Declaring the number.` `n ` `=` `4` ` ` `# Finding square by multiplying them` `# with each other` `square ` `=` `n ` `*` `n` ` ` `# Printing square` `print` `(square)` |

**Output:**

16

**Method 2: Using Exponent Operator**

In this approach, we use the exponent operator to find the square of the number.

Exponent Operator:**

Return:a ** b will return a raised to power b as output.

**Example:**

## Python3

`# Declaring the number.` `n ` `=` `4` ` ` `# Finding square by using exponent operator` `# This will yield n power 2 i.e. square of n` `square ` `=` `n ` `*` `*` `2` ` ` `# Printing square` `print` `(square)` |

**Output:**

16

**Method 3: Using pow() Method**

In this approach, we will use the pow() method to find the square of the number. This function computes x**y and returns a float value as output.

Syntax:float pow(x,y)

Parameters :

x :Number whose power has to be calculated.

y :Value raised to compute power.

Return Value :

Returns the value x**y in float.

**Example:**

## Python3

`# Declaring the number.` `n ` `=` `4` ` ` `# Finding square by using pow method` `# This will yield n power 2 i.e. square of n` `square ` `=` `pow` `(n, ` `2` `)` ` ` `# Printing square` `print` `(square)` |

**Output:**

16.0
