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

```package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

public static void main(String[] args) {

// create 2 BigDecimal Objects
BigDecimal bg1, bg2;

bg1 = new BigDecimal("2.17");

// apply pow method on bg1
bg2 = bg1.pow(3);

String str = "The value of " + bg1 + " to the power of 3 is " + bg2;

// print bg2 value
System.out.println( str );
}
}
```
