Calculate pow(x, n) using the pow( ) Function
PHP provides a built-in function pow( ) to calculate the power of a number. The pow( ) function in PHP is used to calculate the power of a number. It takes two arguments: the base number (‘x’) and the exponent (‘n’). The function returns the result of raising ‘x’ to the power of ‘n’.
Explanation:
- The
pow( )function takes two arguments, the basexand the exponentn, and returnsxraised to the power ofn. - In this example,
pow(2, 3)returns8, which is2raised to the power3.
Example: Implementation to calculate pow(x,n).
PHP
<?php $x = 2; $n = 3; $result = pow($x, $n); echo "$x to the power $n is $result"; ?> |
Output
2 to the power 3 is 8
PHP Program to Calculate pow(x, n)
Calculating the power of a number is a common mathematical operation. In PHP, this can be done using the pow( ) function, which takes two arguments, the base x and the exponent n, and returns x raised to the power of n. In this article, we will explore different approaches to calculate pow(x, n) in PHP, including using the built-in function and implementing custom functions for educational purposes.
