Best ResponseYou've already chosen the best response.1h(100) = 2*4*6...100 if you observe properly, it is written (2^50)*(1*2..50) or (2^50)*(50 !) we are concerned about (2^50)*(50!) +1 note that h(100) and h(100) +1 are both consecutive nos. , thus they dont share ANY common factor apart from 1 . h(100) clearly has all prime factors from 1 to 50 as its factors, thus h(100)+1 cant have those as factors. hence ans would be greater than 50 according to me, or E
