										 |  |  |  | O coeficiente binomial $\displaystyle\binom{10}{3} = 120$. |

 |

											2021-11-15 06:40:48 -08:00
										 |  |  |  | $120 = 2^3 × 3 × 5 = 2 × 2 × 2 × 3 × 5$, and $2 + 2 + 2 + 3 + 5 = 14$. |

											2021-11-15 06:40:48 -08:00
										 |  |  |  | Portanto, a soma dos termos na fatoração de números primos de $\displaystyle\binom{10}{3}$ é $14$. |
