Answer:
A
Step-by-step explanation:
In this problem, first u would have to keep the base of 3, then multiply the two powers together to get -28.
However, u can't leave a negative power in the numerator, so u bring the base and the power down into the denominator, change the sign of the power to make it positive, and put a 1 in the numerator.
From my calculations, I have g = -10
(3 * 15) / 4 = 45/4 = 11....remainder 1....each grandkid gets 11 cards...equaling 44 cards....leaving 1 left for Mr. Dawson
3.2 less days than 16 because each 25 is 5 than 16 divide by 5 is 3.2
