hi, can someone please explain to me how they got from $\displaystyle [\frac{s + n(\mu - \overline{Y})^2}{2}]^{-n/2} $ to $\displaystyle [(1 + \frac{n(\mu - \overline{Y})^2}{s})(\frac{s}{2})]^{-n/2}$ coz i don't get it sorry

Think of it as $\displaystyle \frac{s+ A}{2}$. Factor out a "1/2": $\displaystyle (s+ A)(\frac{1}{2})= (s+ \frac{As}{s})\frac{1}{2}$ and now factor out an "s": $\displaystyle (1+ \frac{A}{s})\frac{s}{2}$.
