You use the exponentiation operator (**) in a webpage for mathematical calculation.
It helps in raising one value (number) to the power of another, which are also called operands, and together with the double asterisk (**), they perform the exponentiation.
Syntax:
$result = $left_operand ** $right_operand;Example:
<?php
$a = 2;
$b = 3;
$exp = $a ** $b;
echo "The power is: ". $exp;
?>Output:
The power is: 8
