## Python code to calculate X raised to power N and print it.

# Input values for x and n x = 2 n = 3 # Calculate x raised to the power of n using the ** operator result = x ** n # Print the result print(result)

### Explanation:

- The code starts by defining two variables
`x`

and`n`

and assigning them the values 2 and 3 respectively. - Next, it calculates
`x raised to the power of n`

by using the ** operator. - The ** operator is used to perform exponentiation, it raises the number to the left of the operator to the power of the number to the right of the operator.
- In this case, the variable
`result`

is assigned the value of`x`

raised to the power of`n`

. - Finally, it prints the result on the screen.

In this example, `x=2`

and `n=3`

so the output will be 8.

Alternatively, you can use the `pow()`

function to calculate the power of a number.

### Output:

result = pow(x,n) print(result)

## JAVA code to calculate X raised to power N and print it.

Here is an equivalent code in Java for calculating x raised to the power of n:

import java.lang.Math; // import the Math library for the pow() function public class Main { public static void main(String[] args) { // Input values for x and n int x = 2; int n = 3; // Calculate x raised to the power of n using the Math.pow() function double result = Math.pow(x, n); // Print the result System.out.println(result); } }

### Explanation:

- The code starts by importing the Math library, which contains the
`pow()`

function. - Then it defines two variables
`x`

and`n`

and assigns them the values 2 and 3 respectively. - Next, it uses the
`Math.pow()`

function to calculate`x`

raised to the power of`n`

. The`pow()`

function takes two arguments: the base and the exponent. - The function returns a double value, so the result is assigned to a double variable
`result`

. - Finally, it prints the result on the screen using the
`System.out.println()`

function.

In this example, `x=2`

and `n=3`

so the output will be 8.0

**Note that in Java, the pow() function returns a double, so the result is stored in a double variable.**

## C++ code to calculate X raised to power N and print it.

Here is an equivalent code in C++ for calculating x raised to the power of n:

#include <iostream> #include <cmath> // include the cmath library for the pow() function int main() { // Input values for x and n int x = 2; int n = 3; // Calculate x raised to the power of n using the pow() function double result = pow(x, n); // Print the result std::cout << result << std::endl; return 0; }

### Explanation:

- The code starts by including the
`iostream`

library for input/output operations and the`cmath`

library, which contains the`pow()`

function. - Then it defines two variables
`x`

and`n`

and assigns them the values 2 and 3 respectively. - Next, it uses the
`pow()`

function to calculate`x`

raised to the power of`n`

. The`pow()`

function takes two arguments: the base and the exponent. - The function returns a double value, so the result is assigned to a double variable
`result`

. - Finally, it prints the result on the screen using the
`std::cout`

function and the`std::endl`

adds a new line after the result.

In this example, `x=2`

and `n=3`

so the output will be 8.

**Note that in C++, the pow() function also returns a double, so the result is stored in a double variable.**
