The general term in the expansion of (x+y)n is :
- A.
nCrxn−ryr
(Correct Answer) - B.
nCrxryn−r
Correct Answer: nCrxn−ryr
Explanation
Binomial Theorem ke anusar, (x+y)n ka purn vistaar (expansion) niche diye gaye equation se hota hai:
(x+y)n=nC0xny0+nC1xn−1y1+nC2xn−2y2+⋯+nCrxn−ryr+⋯+nCnyn
Is pure expansion mein jo term r ki position par depend karta hai, use General Term (Tr+1) kehte hain:
