Problem:
Find the cross product of the following vectors:
$\left(
\begin{array}{c}
 -\frac{49}{10} \\
 \frac{1}{5} \\
 -\frac{21}{10} \\
\end{array}
\right)$ and
$\left(
\begin{array}{c}
 \frac{18}{5} \\
 -\frac{87}{10} \\
 \frac{9}{5} \\
\end{array}
\right)$
Answer:
$\left(
\begin{array}{c}
 -\frac{1791}{100} \\
 \frac{63}{50} \\
 \frac{4191}{100} \\
\end{array}
\right)$
