You haven't defined superscript n.

PS It's usually best to upload your worksheet, not just an image.

The units in your first equation don't balance, neither if we assume n=2, nor for any other value of n.

 

The left hand side is of dimension "length", the right hand side pressure^n * length^(n/2)
