( c - d)^10      7th term

 

The 7th term is as folows :

 

C (10,6) * c^4 * d^6  =

 

210c4d6

 

BTW.... here's the full expansion  as a check ;

 

c^10 - 10 c^9 d + 45 c^8 d^2 - 120 c^7 d^3 + 210 c^6 d^4 - 252 c^5 d^5 + 210 c^4 d^6 - 120 c^3 d^7 + 45 c^2 d^8 - 10 c d^9 + d^10

 

 

cool cool cool
