Answer:
=33
Step-by-step explanation:
87.5% of 32 questions = 28 questions.
32 - 28 = 4
so there are 4 questions to be done after dinner.
Answer:Thus, (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm
So for (-3)-4 , n= -3 and -m= -4 (or m= 4).
Thus, (-3)-4 = 1/(-3)4.
