Answer 1

What about using a smallmatrix?

Code:

\documentclass[a4paper,twoside,12pt]{book}
\usepackage[utf8]{inputenc}
\usepackage{amsmath,bm}
\begin{document}
\[
\bm{\mu^*} =
[\begin{smallmatrix}
 17.0716 & 21.3746 & 31.2462 & 34.2847 & 37.0049 & 43.2856 & 50.8193 & 59.7093
\end{smallmatrix}]
\]
\end{document}
