Step-by-step explanation:

a)

the rule of diviisibility for 3 is that the sum of all the digits in the number should be  multiple of 3.

3+8+7+4+0+2 = 14.

14 is not a multiple of 3. thus, 387402 is not a multiple of 3.

b)

the rule of divisibility of 4 is that the number in the tenth and ones' place of the number should be a multiple of 4.

the number in the tenth and ones place of 9056134 is 34. 34 is not a multiple of 4, hence, 9056134 is also not a multiple of 4.
