Find the value of n :

If `.^nC_2` = `.^nC_4` is

Find n if "^nC_12 = ^nC_8

If .^nC_30=^nC_4 , find n

If "^nC_5= ^nC_12 find n.

If .^nC_8=^nC_2 , find .^nC_2

If .^nC_9=^nC_8 find .^nC_17

sum_(0<=i<=j<=n)^( Find the value of )(i+j)(nC_(i)+nC_(j))

Find the value of ^4nC_(0)+^(4n)C_(4)+^(4n)C_(8)+...+^(4n)C_(4n)

If the second term of the expansion [a^((1)/(13))+(a)/(sqrt(a^(-1)))]^(n) is 14a^(5/2), then the value of (^nC_(3))/(^nC_(2)) is.

find n if .^nC_6: ^(n-3)C_3=33:4
