Question

Expand (6 + x)^6.

Answer 1

\[x^{6}+36*x^{5}+540*x^{4}+4320*x^{3}+19440*x^{2}+46656*{x}+46656\]

Answer 2

46,656 + 46,656x + 19,440x2 + 4320x^3 + 540x^4 + 36x^5 + x^6

46,656 - 46,656x - 19,440x^2 + 4320x^3 + 540x^4 - 36x^5 + x^6

46,656 + 46,656x + 19,440x^2 - 4320x^3 - 540x^4 + 36x^5 + x^6

46,656 - 46,656x + 19,440x^2 - 4320x^3 + 540x^4 - 36x^5 + x^6

Answer 3

those are the choices i have only.

Answer 4

or..
\[\sum_{r=0}^{6} \left(\begin{matrix}6 \\ r\end{matrix}\right)*(6)^{6-r}*(x)^{r}\]

Answer 5

46,656 + 46,656x + 19,440x2 + 4320x^3 + 540x^4 + 36x^5 + x^6

^ thats the answer then?
