 Question from Will, a student: What is exponential form of -8?

Hi Will,

There are many ways to write $-8$ in exponential form, for example $-8 = \left(-2\right)^1 \times 2^2$ or $-8 = \left(-2\right)^1 \times \left(-2\right)^{2}.$ I think what is expected is $-8 = \left(-2\right)^3$ but the question is not clear.
