What is the difference between calculating the square root and the third root in PHP?

Calculating the square root and the third root in PHP involves using different mathematical functions. To calculate the square root of a number, you can use the sqrt() function, while to calculate the third root of a number, you can use the pow() function with a fractional exponent of 1/3.

// Calculate the square root of a number
$number = 16;
$squareRoot = sqrt($number);
echo "Square root of $number is: $squareRoot";

// Calculate the third root of a number
$number = 27;
$thirdRoot = pow($number, 1/3);
echo "Third root of $number is: $thirdRoot";
