# Java.math.BigInteger.pow() Method

## Description

The java.math.BigInteger.pow(int exponent) returns a BigInteger whose value is (thisexponent). The exponent is an integer rather than a BigInteger.

## Declaration

Following is the declaration for java.math.BigInteger.pow() method.

```public BigInteger pow(int exponent)
```

## Parameters

exponent − Exponent to which this BigInteger is to be raised.

## Return Value

This method returns a BigInteger object whose value is thisexponent.

## Exception

ArithmeticException − Exponent is negative. This would cause the operation to yield a non-integer value.

## Example

The following example shows the usage of math.BigInteger.pow() method.

```package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

public static void main(String[] args) {

// create 2 BigInteger objects
BigInteger bi1, bi2;

// create and assign value to exponent
int exponent = 2;

// assign value to bi1
bi1 = new BigInteger("6");

// perform pow operation on bi1 using exponent
bi2 = bi1.pow(exponent);

String str = "Result is " + bi1 + "^" +exponent+ " = " +bi2;

// print bi2 value
System.out.println( str );
}
}
```

Let us compile and run the above program, this will produce the following result −

```Result is 6^2 = 36
```
