Lisbeth says that the solution to (-12) to the -3 power will be positive do you agree? explain your answer

You should disagree here. Negative twelve to the power of negative three is the same as -12 ×-12×-12.

The first -12 × -12 will equal positive 144. However, the next multiplication step will take 144 × -12. This will result in a negative 1,728 (I think). so yeah. disagree.
