Which shows the following expression after the negative exponents have been eliminated? a^3 b^-2 / ab^-4 , a=/0 , b=/0

Are there options? otherwise, i’d say afghanistan, cyprus, comoros, eritrea, and more are a couple examples of oil-dry countries. let me know if one of those was an option!

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
