Can someone help please

k = 5

Step-by-step explanation:

Box A has more counters than box B

3 * 4 = 12

4 + 8 = 12

So if k was equal to 4, then both boxes would have the same amount.

3 * 5 = 15

5 + 8 = 13

15 > 13

If k was equal to 5, then Box A would contain more counters than Box B.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
