Ajutor!Multumesc anticipat!​

Answer 1

Răspuns:

P=2021

Explicație pas cu pas:

$P = \frac{1 + 1}{1} \times \frac{2 + 1}{2} \times \frac{3 + 1}{3} \times ... \times \frac{2020 + 1}{2020}$

$P = \frac{2}{1} \times \frac{3}{2} \times \frac{4}{3} \times ... \times \frac{2021}{2020}$

$P = \frac{2021!}{2020!}$

$P = 2021$
