If m and n are the coeficients of `x^(a^(2)) and x^(b^(2))` respectively in `(1+x)^(a^(2)+b^(2))`, then ____________A. `n=2m`B. `m+n=0`C. `2n=m`D. `m=n`

If m and n are the coeficients of `x^(a^(2)) and x^(b^(2))` respective

1.	If m and n are the coeficients of `x^(a^(2)) and x^(b^(2))` respectively in `(1+x)^(a^(2)+b^(2))`, then ____________A. `n=2m`B. `m+n=0`C. `2n=m`D. `m=n`
Answer» Correct Answer - D (i) `"Use"""^(n)C_(r)=""^(n)C_(n-r)` (ii) `m=(a^(2)+b^(2))c_(a^(2))x^(a^(2)) and=(a^(2)+b^(2))c_(b^(2))x^(b^(2))` (ii) Find.
