Answer:
The unit of 70.5 is lbm/ft^3
The unit of 8.27×10^7 is in^2/lbf
Explanation:
The unit of 70.5 has the same unit as density which is lbm/ft^3 because exponential is found of constant values (unitless values)
The unit of 8.27×10^7 (in^2/lbf) is the inverse of the unit of pressure P (lbf/in^2) because the units have to cancel out so a unitless value can be obtained. Exponential is found of figures with no unit
