The value of P(n,n) is

Find the value of   P( n , n -1 )

What is the value of n, if P(15, n -1) : P(16, n -2) = 3 : 4 ?

Let alpha and beta be two real numbers such that alpha+beta=1 and alpha beta=-1 Let p_(n)=(alpha)^(n)+(beta)^(n), p_(n-1)=11 and p_(n+1)=29 for some integer n geq 1 Then, the value of p_(n)^(2) is

If ""^(n)P_r = ""^(n)P_(r+1) and ""^(n)C_r = ""^(n)C_(r-1) ,then the values of n and r are

If p^(2)-p+1=0 , then the value of p^(3n) can be
