JavaScript Math pow() method example

Here, we will understand pow() method through various examples.

Example 1

Let's see a simple example to print the power of given number.

<script>
document.writeln(Math.pow(2,3)+"<br>");
document.writeln(Math.pow(5,1.4));
</script>

Test it Now

Output:

8
9.518269693579391

Example 2

Let's see an example to understand the pow() method with different test cases.

<script>
document.writeln(Math.pow(2,-3)+"<br>");
document.writeln(Math.pow(-3,2)+"<br>");
document.writeln(Math.pow(-5,1.4)+"<br>");
document.writeln(Math.pow(5,-1.4));
</script>

Test it Now

Output:

0.125
9
NaN
0.1050611121761507

Example 3

Let's understand the pow() method with your own test cases.

<script>
function display()
{
  var x=document.getElementById("base").value;
  var y=document.getElementById("exp").value;
  
  document.getElementById("result").innerHTML=Math.pow(x,y);
}
</script>
<form>
Base: <input type="text" id="base"><br>
Exponent: <input type="text" id="exp"> <br>
  <input type="button"  onclick="display()" value="submit">
</form>
<p><span id="result"></span></p>
