T* (k+1) = C(^k;_n)* a^^(n-k)* b^^k $T\cdot (k+1)$ = $C_{n}^{k}\cdot a^{(n-k)}\cdot b^{k}$

T* (k+1) =

a^^(n-k)* b^^k* n!

/ (n-k)!/ k!

$T\cdot (k+1)$ = $\frac{a^{(n-k)}\cdot b^{k}\cdot n!}{(n-k)!\cdot k!}$

T =

/ (n-k)!/ k!/ (k+1)

$T$ = $\frac{a^{(n-k)}\cdot b^{k}\cdot n!}{(n-k)!\cdot k!\cdot (k+1)}$

T =
