${\displaystyle (a+b)^{1}=a+b\,}$

${\displaystyle (a+b)^{2}=a^{2}+2ab+b^{2}\,}$

${\displaystyle (a+b)^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3}\,}$

${\displaystyle (a+b)^{4}=a^{4}+4a^{3}b+6a^{2}b^{2}+4ab^{3}+b^{4}\,}$

${\displaystyle (a+b)^{5}=a^{5}+5a^{4}b+10a^{3}b^{2}+10a^{2}b^{3}+5ab^{4}+b^{5}\,}$

${\displaystyle (a+b)^{n}={\binom {n}{0}}a^{n}+{\binom {n}{1}}a^{n-1}b+...+{\binom {n}{n}}b^{n}}$

${\displaystyle {\binom {n}{k}}={\frac {n!}{k!(n-k)!}}}$

${\displaystyle {\binom {n+1}{k}}={\binom {n}{k-1}}+{\binom {n}{k}}}$
