# How to use Math power in JavaScript [SOLVED]

## Introduction

Numbers are important, and within JavaScript, there are different ways to work with them. Interestingly, there are two data types - `Number` and `BigInt` - that we can make use of when working with numbers. Different calculations can be made within JavaScript from additions to divisions and even to complex operations such as logarithmic operations.

However, our focus is exponentiation, where we raise a number to the power of another number. How do we execute math power operations in JavaScript? Thatโs what this article intends to explain.

## Different methods to execute Math Power in JavaScript

JavaScript makes provision for two approaches to execute exponentiation operations. These approaches are the `**` operator and the `pow` method namely.

### Method-1: The `**` operator

The ** operator accepts both `Number` and `BigInt` datatype operands, and allows us to infuse it within typical JavaScript statements and assignments. Letโs illustrate ways to use the `**` operator in different ways and contexts.

``````const power = 3;
const number = 4;

console.log(number ** power);
``````

Output

```64
```

But whatโs beautiful about this is that we can use the operator with the assignment operator. In the example below, we raise the value of the `num` binding to the power of 2 using the exponentiation assignment operator, `**=`.

``````let num = 5;
num **= 2;
console.log(num);
``````

Output

```25
```

Also, it works with `BigInt`.

``````let num = BigInt(23456121);
num **= BigInt(2);
console.log(num);
``````

Output

```550189612366641n
```

### Method-2: The `pow` method

JavaScript has a Math object that contains static properties and methods, and the `pow` method is one of the many. To perform math power operations, theย `Math.pow()` method returns the value of a base raised to a power, but whatโs important is that it only works with the `Number` data type.

Letโs play with the `pow` method by raising the number 4 to the power of 3.

``````const power = 3;
const number = 4;

console.log(Math.pow(number, power));
``````

Output

```64
```

## Summary

To perform math power operations in JavaScript, we can make use of the `**` operator and the `pow` method, however, only the `**` operator works with the `Number` and `BigInt` data type.
