Question

Simplifique em forma de fração -> 4!+6!/5!

Answer 1

$\frac{4!+6!}{5!}=\frac{4!+6.5.4!}{5.4!}=\frac{1+30}{5}=\frac{31}{5}$

Answer 2

4! = 4.3.2.1 = 24
6! = 6.5.4.3.2.1 = 720
5! = 5.4.3.2.1 = 120


$\frac{4!+6!}{5!} = \frac{24 +720}{120} = \frac{744:4}{120:4} = \frac{186:2}{30:2} = \boxed{\frac{93}{15} }$
