Question

(1+1/2)*(1+1/3)*(1+1/4)*........*(1+1/2020).Va rog ajutati-ma

Answer 1

Răspuns:

Explicație pas cu pas:

1+1/2=2/2+1/2=3/2

1+1/3=3/3+1/3=4/3

1+1/4=4/4+1/4=5/4

-----------------------------

1+1/2020=2020/2020+1/2020=2021/2020

ex devine

3/2*4/3*5/4*.......*2020/2019*2021/2020

se simplifica 3,  4,  5.......2020

ramane = 2021/2=1010,5
