Answer 1

Explicação passo-a-passo:

a)

$\dfrac{124!}{122!} =\dfrac{124.123.122!}{122!} \\\\\dfrac{124!}{122!}=124.123\\\\\boxed{\boxed{\dfrac{124!}{122!}=15252}}$

b)

$\dfrac{32!}{31!} =\dfrac{32.31!}{31!} \\\\\boxed{\boxed{\dfrac{32!}{31!} =32}}$

c)

$\dfrac{240!}{238!} =\dfrac{240.239.238!}{238!} \\\\\dfrac{240!}{238!}=240.239\\\\\boxed{\boxed{\dfrac{240!}{238!}=57360}}$
