Starting from this old this question
How to make fractions in powers look good, I'm searching a optimal solution to aesthetically define a fraction of the type \frac{...}{...}
. For my book I've used the 2nd formula as in the image (green line),
but I'm not very happy about the results.
(a) Meanwhile I would like to understand if there is any minimal difference between the second and fifth formula.
(b) After, I'd like to know how to build the smallest power ^{-\frac{3}{2}}
in size and aesthetically more beautiful and that it's higher left near the round bracket )
. In fact if you look carefully this fraction is almost close to the next x
.
Here there is my MWE. Thank you.
