(1 point) Responses Shane is correct because all that needs to be done is to make the negative exponents positive. Shane is correct because all that needs to be done is to make the negative exponents positive. 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. 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. None of these are correct because the students did not add the exponents in the numerator and then subtract exponents since there is division. None of these are correct because the students did not add the exponents in the numerator and then subtract exponents since there is division. Adam is correct because the negative exponent combines with the base and the denominator moves to the numerator.

Answer 1

The correct answer is None of these are correct because the students did not add the exponents in the numerator and then subtract exponents since there is division.

The expression simplifies to:
32 * 3 - 15 - 2 * 20
= 96 - 15 - 40
= 81 - 40
= 41
