nteger type questions :
If n(A)=9. n(B) = 27, then n(A x B) = 34. The value of k is​

Answer 1

Answer:

Clearly, rn > 1 for each n, so that from (b), rn+1 - rn and rn - rn-I have ... For each positive integer k, let P2k = Xk and q2k = 2Yk. ... 8), while if y is odd, then x 2 == 5 (mod 8); neither congruence for x 2 is ... n(n + 1) - 1 = m2 can be rewritten as (2n + 1)2 - 8m2 = 9. ... ing solutions (x, y) = (2,1), (-7, -4), (-2, -1). d = 27 is covered.
