I ran into an equation while checking FAR part 23 to see if my design would pass. The equation appears to want the tangent of the hull deadrise angle taken to the power of 2/3 and the seaplane weight taken to the power of 1/3. I have never seen numbers taken to the power of fractions before and wondered if I was reading the equation correctly. We've all seen squares, cubes etc but fractions?

Any one wanting to see the equation I am refering to it is FAR 23 sub 23.527 (2) "Hull and main float load factors" (a) (1)&(2).

I have no idea how to write the equation out for you or I would.

Thanx
