Question

Consider this equation:

Answer 1

E. Because 27^-1 = 1 because you have to flip the number to get positive fraction (if there is a negative in the exponent) over 21 (1/27), therefore a fraction raised to a power gives you a smaller fraction soooo 1/3^3 gives you a positive 1/27

Answer 2

A and B are equal to 27^-1
