Q 16 is pretty easy! Just multiply the given expression in question with 1-q and you end up with 1+q^128 .But that's not the final answer as you multiplied the expression with 1-q, so to get the final answer, undo your trick by dividing 1+q^128  by 1-q, so (1+q)(1+q^2)(1+q^4)(1+q^8)(1+q^16)(1+q^32)(1+q^64)=(1+q^128)/1-q .

Q 51 Draw venn diagram, focus on the intersections. Then it is very easy to come up with answer within a minute. Note that students who are failed in all papers are the same who could not even at least pass one paper.
