`n in NN` হলে `n(n + 1)(n + 2)` এবং `n(n + 1)(n+ 5)` রাশিমালা দুটি—

Find n if : ""^(2n+1) P_(n-1) : ""^(2n-1) P_n = 3: 5

If ninNN , both expression n(n+1)(n+2) and n(n+1)(n+5) are multiple of -

If n in N and Delta_ (n) = det [[n!, (N + 1)!, (N + 2)! (N + 1)!, (N + 2)!, (N + 3)! ( n + 2)!, (n + 3)!, (n + 4)!]] then lim_ (n rarr oo) ((3 ^ (n ^ (3)) - 5) Delta_ (n)) / (Delta_ (n + 1)) equals

If N_a =[an : n in N], " then " N_5 nn N_7 is equal to : a) N_7 b)N c) N_(35) d) N_5

If n(A) denotes the number of elements in set A and if n(A) = 4, n(B) = 5 and n(A nn B) =3 then n[(A xx B) nn (B xx A)]=

If n(A) denotes the number of elements in set A and if n(A) = 4, n(B) = 5 and n(A nn B) =3 then n[(A xx B) nn (B xx A)]=

If n(A) denotes the number of elements in set A and if n(A) = 4, n(B) = 5 and n(A nn B) =3 then n[(A xx B) nn (B xx A)]=

Let NN be the set of positive integers. For all n in NN , let f_n=(n+1)^(1/3)-n^(1/3) and A={n in NN:f_(n+1)<1/(3(n+1)^(2/3))
