Question

URGENTEE me ajudem por favor preciso hoje

Answer 1

a) 4!

4.3.2.1 = 24

===
b)

3 . 0!   => 0! = 1
3 . 1 = 3

====
c)

5! - 4!

5.4.3.2.1 - 4.3.2.1
120 - 24
=> 96
====
d)

$\dfrac{10!}{7!} \\ \\ \\ \dfrac{10 . 9. 8 .\not7!}{\not7!} \\ \\ \\ 10 . 9 . 8 =\ \textgreater \ 720$

===
e)

$\dfrac{8! . 5!}{7! . 5!} \\ \\ \\ \dfrac{8 . \not7! . \not5!}{\not7! . \not5!} = 8$

===
f)

$\dfrac{8! + 5!}{5!} \\ \\ \\ \dfrac{8.7.6,\not5! + 1 \not5!}{\not5!} \\ \\ \\ =\ \textgreater \ 8.7.6 + 1 = 337$

===
g)

$\dfrac{9!}{7!} \\ \\ \\ \dfrac{9 . 8 . \not7!}{\not7!} \\ \\ \\ =\ \textgreater \ 9 . 8 = 72$

===
h)

$\dfrac{20!}{18!} \\ \\ \\ \dfrac{20 . 19 . \not18 !}{\not18!} =\ \textgreater \ 380$

====
i)

$\dfrac{48! + 49!}{50!} \\ \\ \\ \dfrac{1 + \not48! + 49. \not48!}{50.49.\not48!}\\ \\ \\ \dfrac{1 + 49}{50.49} \\ \\ \\ \dfrac{\not50}{\not50.49}\\ \\ \\ \dfrac{1 }{49}$

===
j)

$\dfrac{7!}{4!} \\ \\ \\ \dfrac{7. 6. 5. \not4!}{\not4!} \\ \\ \\ 7 . 6 . 5 = 210$

====
k)
$\dfrac{3! . 5!}{4! . 6!}\\ \\ \\ \dfrac{\not3! . \not5!}{4 . \not3! . 6. \not5 !} \\ \\ \\ \dfrac{1}{6 . 4}\\ \\ \\ \dfrac{1}{24}$

====
L)

$\dfrac{12!}{10! + 9!} \\ \\ \\ \dfrac{12.11. 10 . \not9!}{10. \not9! + \not9!}\\ \\ \\ \dfrac{12. 11 . 10 }{10 + 1}\\ \\ \\ =\ \textgreater \ \dfrac{1320}{11} = ~ 120$
