    x to the power of n is done via: $x ** $n or
    sub x_power_n { my $x = shift; my $n = shift; my $result = $x; my $i = 1; while ($i < $n) { $result *= $x; $i++; } return $result; }
    You need to do this, though, "infinite" times, reason why I provided a parameter to "stop" after a certain time.

      That only works for integer exponents. The equation in the OP handles real numbers.

      Using exp and ln, it's possible to find any exponent.
