## Will there ever be a scenario

## Yes, it's possible to be

Yes, it's possible to be required to evaluate a power like 729^(-0.333.....), just as long as the decimal can be converted to a decimal (e.g., -0.333333.... can be rewritten as -1/3)

In this case, 729^(-0.333.....) = 729^(-1/3) = 1/(729^1/3) = 1/9

Cheers,

Brent
