How do you find a book in the library? You should look in the card index. These  cards show the subjects. They are in alphabetical order There are two sets of cards in the library One is authors and the other is titles If you know both the author's name and the title of the book, you can find it very easy. If the book isn't on the shelf, ask the librarian to get it for you.

Giải:
Gọi 3 số đó là a, b, c

Ta có: \(\frac{a}{\frac{2}{5}}=\frac{b}{\frac{3}{4}}=\frac{c}{\frac{1}{6}}\)\(a^2+b^2+c^2=24309\)

Đặt \(\frac{a}{\frac{2}{5}}=\frac{b}{\frac{3}{4}}=\frac{c}{\frac{1}{6}}=k\Rightarrow\left\{\begin{matrix}a=\frac{2}{5}k\\b=\frac{3}{4}k\\c=\frac{1}{6}k\end{matrix}\right.\)

\(a^2+b^2+c^2=24309\)

\(\Rightarrow\frac{4}{25}k^2+\frac{9}{16}k^2+\frac{1}{36}k^2=24309\)

\(\Rightarrow\frac{2701}{3600}k^2=24309\)

\(\Rightarrow k^2=32400\)

\(\Rightarrow\left\{\begin{matrix}k=180\\k=-180\end{matrix}\right.\)

+) \(k=180\Rightarrow a=72;b=135;c=30\)

\(\Rightarrow a+b+c=237\)

+) \(k=-180\Rightarrow a=-72;b=-135;c=-30\)

\(\Rightarrow a+b+c=-237\)

Vậy \(\left[\begin{matrix}a+b+c=237\\a+b+c=-237\end{matrix}\right.\)
