Đoàn thanh niên Q10 tổ chức chức chương trình phát khẩu trang miễn phí để góp phần nâng cao tính thần phòng chống dịch Covid-19. Ngày thứ nhất phát đc 1/2 số khẩu trang. Ngày thứ2 phát đc 1/2 số khẩu trang còn lại. Sau hai ngày còn lại 125 khẩu trang. Hỏi tổng số khẩu trang mà đoàn thanh niên đã chuẩn bị để phát là bao nhiêu?
1) Số tự nhiên n thỏa mãn\(\frac{n+3}{2n-2}\) có giá trị nguyên là ...
2)Cho Q=\(\frac{1}{30}+\frac{1}{42}+\frac{1}{56}+\frac{1}{72}+\frac{1}{90}\)Khi đó Q10=
giúp mềm
Q10 là 10.Q????
1) Ta có: \(\frac{n+3}{2n-2}\)\(=\frac{n+3}{2\left(n-1\right)}\)
Để \(\frac{n+3}{2\left(n-1\right)}\in Z\) thì \(\left\{{}\begin{matrix}n+3\in Z\Rightarrow n\in Z\\2\left(n-1\right)\in Z\Rightarrow n\in Z\\2\left(n-1\right)\ne0\Rightarrow n-1\ne0\Rightarrow n\ne1\end{matrix}\right.\)
Vậy để \(\frac{n+3}{2n-2}\in Z\) thì: \(n\in Z;n\ne1\)
mà n là số tự nhiên \(\Rightarrow n\in N;n\ne1\)
Vậy: Để \(\frac{n+3}{2n-2}\in Z\) thì: n\(\in N;n\ne1\)
2) Ta có: \(Q=\frac{1}{5.6}+\frac{1}{6.7}+\frac{1}{7.8}+\frac{1}{8.9}+\frac{1}{9.10}\)
\(\Leftrightarrow Q=\frac{1}{5}-\frac{1}{6}+\frac{1}{6}-\frac{1}{7}+...+\frac{1}{9}-\frac{1}{10}\)
\(\Leftrightarrow Q=\frac{1}{5}-\frac{1}{10}=\frac{1}{10}\)
\(\Leftrightarrow10.Q=10.\frac{1}{10}=1\)

Hello, my name is Hoa. I’d like to be a teacher in the future. I’d like to teach children to read, write, do math, and much more. I’d like to try to make my lessons easy to understand. I’d like to make posters or worksheets, use games, videos, computers, a chalkboard, a projector and other tools to teach children different subjects.
