If m and n are the coeficients of x^(a^(2)) and x^(b^(2)) respectively in (1+x)^(a^(2)+b^(2)), then relation between m and n is ____________

Answer»

`n=2m`
`m+n=0`
`2n=m`
`m=n`

SOLUTION :(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.
