Answer:
a positive even number.
Step-by-step explanation:
I suggest plugging in random positive even numbers and finding a pattern. (-12)^2 = 144. (-12)^ 4= 20,736. this is because two negatives, when multiplied, turn to a positive. the n is how many times negative 12 is multiplied with itself
0.875 as a fraction is 7/8 because 875/100 is equal to 7/8
