Chapter 12: Q. 217E (page 1213)

In the following exercises, expand each binomial.
$(s + t)^{7}$

Short Answer

Expert verified

Expansion is $s^{7} + 7 s^{6} t + 21 s^{5} t^{2} + 35 s^{4} t^{3} + 35 s^{3} t^{4} + 21 s^{2} t^{5} + 7 s t^{6} + t^{7}$

Step by step solution

Given Information

Expand $(s + t)^{7}$

Solution

We have

$(s + t)^{7} = (\begin{matrix} 7 \\ 0 \end{matrix}) s^{7 - 0} t^{7 - 7} + (\begin{matrix} 7 \\ 1 \end{matrix}) s^{7 - 1} t^{7 - 6} + (\begin{matrix} 7 \\ 2 \end{matrix}) s^{7 - 2} t^{7 - 5} + (\begin{matrix} 7 \\ 3 \end{matrix}) s^{7 - 3} t^{7 - 4} + (\begin{matrix} 7 \\ 4 \end{matrix}) s^{7 - 4} t^{7 - 3} + (\begin{matrix} 7 \\ 5 \end{matrix}) s^{7 - 5} t^{7 - 2} + (\begin{matrix} 7 \\ 6 \end{matrix}) s^{7 - 6} t^{7 - 1} + (\begin{matrix} 7 \\ 7 \end{matrix}) s^{7 - 7} t^{7 - 0} = s^{7} + 7 s^{6} t + 21 s^{5} t^{2} + 35 s^{4} t^{3} + 35 s^{3} t^{4} + 21 s^{2} t^{5} + 7 s t^{6} + t^{7}$
