Answer:
the product of 5 and a number
5n5n is really 5 * n5∗n .
In higher education math, the multiplication sign is not used. A number and a variable (or a equation in grouping symbols) would be just together next to each other. When it's like this, you would have to multiply the numbers.
Example:
\begin{gathered}4n; n = 2\\4(2) = 4* 2 = 8\end{gathered}
4n;n=2
4(2)=4∗2=8
