Question

Calcule a fatorial : 5! . 8!/4! . 6!

Answer 1

$\frac{5! \cdot 8!}{4! \cdot 6!} = \frac{5 \cdot 4! \cdot 8 \cdot 7 \cdot 6!}{4! \cdot 6!} = \frac{5 \cdot \not 4! \cdot 8 \cdot 7 \cdot \not 6!}{\not 4! \cdot \not 6!} = 5 \cdot 8 \cdot 7 = \boxed{\boxed{280}}$

Answer 2

$\dfrac{5!. 8!}{4!.6!} = \dfrac{5.4!. 8.7.6!}{4!.6!} = \dfrac{5.\not 4!. 8.7.\not 6!}{\not 4!.\not 6!} =5.8.7=280$
