Câu 1 sai,mik sửa luôn rồi đấy k mik nha

\(\text{1. What's time is it?
2. What do they do in the evening?}\)
\(\text{3. What time does your mother get up in the morning?
4. When do we have Math?
}\)
\(\text{5. Who does the housework everyday?}\)

(1-1/2)(1-1/3)(1-1/4)...(1-1/2009)
=1/2*2/3*3/4*...*2008/2009
=\(\frac{1\cdot2\cdot3\cdot...\cdot2008}{2\cdot3\cdot4\cdot...\cdot2009}\)
=1/2009

=> 1/2.2/3.3/4...x/(x+1)=1/2009
=> 1/(x+1)=1/2009
=> x+1=2009
=> x=2008
Mik nhanh nhất mik nha
=> 1/2 . 2/3 . 3/4 .... x/x+1 = 1/2009
<=> (1.2.3...x) / [2.3...x.(x+1)] = 1/2009
<=> 1/ (x+1) = 1/2009
=> x+1=2009 => x=2008
Good morning
Chào buổi sáng 😊
