Your Answer for Question 1:
N inputs --> 2^N combinations --> 2^N outputs --> possibly 2^N logic 1 for the output. So there are possible 2^N number of terms. This is the reason why we need to simplify canonical sum-of-products representation.



Your Answer for Question 2:
A bus is a collection of transmitting wires used to carry signals, which is a small DC current with 2 different voltages.

Your Answer for Question 3:
y = a.a + a.(b + not(b)) (distribute)
y = a.a + a.(1) (inverse)
y = a.a + a (identity)
y = a.(a + 1) (distribute)
y = a.1 (one law)
y = a (identity)
