有什么方法可以写出数字三十七从下图中可以看到同一行上有等号？
\textbf{3.} Afla\c ti de\^ imp\u ar\c titul \c stiind c\u a \^ intre \^ imp\u ar\c titor, c\^ at \c si rest avem rela\c tia $i^2+c^2+r^2=37$.
谢谢！

我不会像 John Kormylo 建议的那样将数学公式括在里面\mbox，而是定义一个禁止在数学公式中换行的命令。事实上，这允许公式中的粘连可以与同一行上的其他粘连一起拉伸和收缩，而 John 的解决方案则不会。

\begin{document}
Some meaningless text, inserted just to get near\ldots\ the end of the line.
\( x+y=a+b\prohibitmathbreaks \).
And some more random text that adds other lines, which~contain~an unbreakable
sequence of words, to show that the spaces inside the formula \emph{are} allowed
to shrink.
On the other hand, if one uses the \verb|\mbox| solution, this does not happen:
\mbox{\( x+y=a+b \).}
And: some more random text that adds other lines, which~contain
unbreakable~sequences~of~words.
Another paragraph, containing another formula, in order to show that the effect
of our \verb|\prohibitmathbreaks| command is kept local:
\( a+b+c+d+e = x+y+z \).
\end{document}
输出：
