I am trying to replicate this formula with LaTeX:
However, I am struggling to make the fraction look the same. This is my attempt:
\begin{equation}
\label{eq:alphaK}
\alpha(k) = \frac{1}{(N-k)} \nicefrac{ \left( \displaystyle \sum_{i=k+1}^{N} \lambda_i \right) }{\left( \displaystyle \prod_{i=k+1}^N \lambda_i \right)^{\frac{1}{N-k}}}
\end{equation}
Which results in the following:
I am looking for a way to increase the size of the "slash" (/) that separates the numerator and denominator. I know I could use a normal \frac
instead of \nicefrac
but I like how it looks when num/den are displayed side by side.
Is there any way I can force the fraction to look more like the first pictured one?
