2Power 2007 plus 5 be equal to Pand let P square=225N,then what is sum of the no.s of N?

Question

HERE 225N does'nt means 225(N).225N
completely is an integer or whole no.

Answer 1

If P^2 = 225N and N is an integer, then P must be divisible by 15 (15^2 = 225). But 2^k + 5 can never be divisible by 5, and 2^2007 + 5 is not divisible by 3 either (2 is congruent to -1 modulo 3, so 2^2007 is congruent to (-1)^2007 = -1). So the question doesn't really make a lot of sense. N will be an infinitely repeating decimal and the sum of its digits isn't really a sensible concept.

Answer 2

oh yeah, i get it... i thought it was pand(Pand).. sorry
