Negative number to fractional power - What is the solution?

Hello, I'm wondering what is the solution of this kind of equation. For example (- 8) to power 1/3, will solution be (-2) or equation is not defined?

As far as I know it's possible to convert the number with power to the form of root. And cubic root of (-8) equals to (-2). But I've checked this equation in Photomath and got "not defined". Why?

I am a little bit confused so I would like to know what is the correct answer for my question. Thanks :)
