n ज्ञात कीजिए `P(2n,3)=100P(n,2)`.

Find n if : P(2n, 3) = 100 P(n,2)

Prove that P(n,n)=2.P(n,n-2)

Find n if : 2P( n,3) = P(n+1,3)

Prove that : P(n,n)= 2P (n,n -2)

Find 'n' if : (i) ""^(2n)P_(3)=100 ""^(n)P_(2) (ii) ""^(n)P_(4)=20xx ""^(n)P_(2)

(i) If ""^(n)P_(5)=20xx""^(n)P_(3) , find n. (ii) If 16xx""^(n)P_(3)=13xx""^(n+1)P_(3) , find n. (iii) If ""^(2n)P_(3)=100xx""^(n)P_(2) , find n.

If P(n,5):P(n,3)=2:1 find n

Prove the following: P(n,n)=2P(n,n-2)

If P(n ,5): P(n ,3)=2:1 find n
