**Given a number, and we have to calculate its square in Python.**

**Example:**

Input:
Enter an integer numbers: 8
Output:
Square of 8 is 64

**Calculating square** is a basic operation in mathematics; here we are calculating the square of a given number by using 3 methods.

- By multiplying numbers two times: (number*number)
- By using Exponent Operator (**): (number**2)
- By using math.pow() method: (math.pow(number,2)

## 1) By multiplying numbers two times: (number*number)

To

find the square of a number- simple multiple the number two times.Program:Output## 2) By using Exponent Operator (**): (number**2)

The another way is to

find the square of a given numberis to useExponent Operator(**), it returns the exponential power. This operator is represented by **Example:Statement m**n will be calculated as"m to the power of n".Program:Output## 3) By using math.pow() method: (math.pow(number,2)

pow(m,n) is an inbuilt method of math library, it returns the value of

"m to the power n". To use this method, we need to import math library in the program.The statement to import math library is import math.
