If `""^(n)C_(12)=""^(n)C_(8),` then n is equal to

If ""^(n+1)C_(3)=4(""^(n)C_(2)) , then n is equal to

In ""_(n)C_(12)=""_(n)C_(8) then n=

If ""^(n)C_(5)=""^(n)C_(10) then n equals :

If .^(n^(2)-.^(n))C_(2)=.^(n^(2)-n)C_(4) , then n is equal to

If .^(n)C_(12)=.^(n)C_(8) then find the value of .^(22)C_(n) .

(i) If ""^(n)C_(8)= ""^(n)C_(2) , find ""^(n)C_(2) . (ii) If ""^(n)C_(10)= ""^(n)C_(12) , determine n and hence ""^(n)C_(5) . (iii) If ""^(n)C_(9)= ""^(n)C_(8) , find ""^(n)C_(17) .
