Who was correct and why?
(1 point)
A None of these are correct because the students did not add the exponents in the numerator and then subtract exponents since there is division.
B Nick is correct because the negative exponent in the numerator can combine with the like base and the denominator negative exponent goes to the numerator.
C Adam is correct because the negative exponent combines with the base and the denominator moves to the numerator.
D Shane is correct because all that needs to be done is to make the negative exponents positive.
