Question

resolva 8!3!/5!6!
por favor urgente

Answer 1

olá

é fatorial

8!3!= 8!7!6! 3!= 56=

5!6!=5!4!3! 6!= 20= 2,8

corte 6 com o 6 sobra 8×7=56

corte 3! com 3! sobra 5×4=20

espero que esteja esteja certo.

☔ Inicialmente  vamos simplificar nossa fração abrindo só um pouquinho nossos números escritos na forma fatorial e conforme a fração ficar mais "limpa" faremos os cálculos

.

➡ $\sf\large\blue{  \dfrac{8 \cdot 7 \cdot 6! \cdot 3!}{5 \cdot 4 \cdot 3! \cdot 6!} }$

➡ $\sf\large\blue{  \dfrac{8 \cdot 7 \cdot \diagup\!\!\!\!{6!}}{\diagup\!\!\!\!{6!}} \cdot \dfrac{\diagup\!\!\!\!{3!}}{5 \cdot 4 \cdot \diagup\!\!\!\!{3!}} }$

➡ $\sf\large\blue{ 8 \cdot 7 \cdot \dfrac{1}{5 \cdot 4} }$

➡ $\sf\large\blue{ \dfrac{56}{20} }$

➡ $\sf\large\blue{ \dfrac{28}{10} }$

➡ $\sf\large\blue{ 2,8 }$
