It looks fine as it is. If that is not working try:

_exponent = 1;
_reciprocal = (x - 1);
if (_reciprocal > 0) {
_result = _reciprocal ^ _exponent;
} else {
hint "Reciprocal was negative! Try applying a negative exponent instead!";
};

I dont think ARMA, or many math libs for that matter can apply exponents to a negative number. The exponent however - can be negative. This is effectively functional division.
