r=0,1,......10 के लिए, माना A^(r), B^(r)...

r=0,1,......10 के लिए, माना `A^(r), B^(r)" तथा " C^(r)` क्रमश: प्रदर्शित करते है `(1+x)^(10), (1+x)^(20)"तथा " (1+x)^(30)` के प्रसार में `x^(r)` के गुणांक को 1 तब `sum_(r=1)^(10) Ar(B_(10)B_(r)-C_(10)A_(r))`बराबर है

A

`B_(10) - C_(10)`

B

`A_(10)(B_(10)^(2) - C_(10) A_(10))`

C

0

D
