I f we take n = 1 and n = 0 we get QA< Qb When n=0 QA is 0, & QB is 1 so QB > QA

NOW, take N = 1 QA is 1 and QB is 100 SO HERE ALSO Qb> QA. How we would know that we have to put vlaues matching to the question as u have palced value of n = 100 here



You have already got B greater than A for sone values of n..

Now we don't have to prove A is greater but..
The similarities in terms 100^n and n^(100) should tell you that n as 100 will make both equal..

So choose 100 and you have different possibilities that give you D as the answer
