What is the simplified form of ( \frac{(n+3)!}{n!}-\frac{(n+2)!}{(n-1)!} )?( \frac{(n+3)!}{n!}-\frac{(n+2)!}{(n-1)!} ) का सरल रूप क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (3(n+1)(n+2))(3(n+1)(n+2))
The first term is ((n+3)(n+2)(n+1)) and the second is (n(n+1)(n+2)), so the difference is (3(n+1)(n+2)). Take common factors out.पहला पद ((n+3)(n+2)(n+1)) और दूसरा (n(n+1)(n+2)) है, इसलिए अंतर (3(n+1)(n+2)) है। समान गुणकों को बाहर निकालें।
