When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV1.4=C where C is a constant. Suppose that at a certain instant the volume is 330 cubic centimeters and the pressure is 99 kPa and is decreasing at a rate of 12 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant?

not sure of your equation,
is it (PV)^1.4 = C
or
P(V^(1.4)) = C
or
1.4PV = C , (usually we don't write a multiplier after the variable like in yours)
is it (PV)^1.4 = C
or
P(V^(1.4)) = C
or
1.4PV = C , (usually we don't write a multiplier after the variable like in yours)
