The formula for change in altitude with air pressure in the lower atmosphere (about to 35,000 feet) is:

Nope.  From what's left of your formula, I'll assume you're trying to
calculate the air pressure at a given altitude.  There is no *change*
in altitude involved.  Looks like you lost all the Greek letter
symbols and formula symbols.

That unreadable mess should look something like these:

"Atmospheric Pressure Calculator"
<https://calculator.academy/atmospheric-pressure-calculator/>

"Air Pressure at Altitude Calculator"
<https://www.omnicalculator.com/physics/air-pressure-at-altitude>

Note that you need to know the barometric base pressure (Pb) at sea
level for such a calculation to work.  It's NOT going to work if your
riding up or down a hill where the barometric pressure might change.
