yes anything with exponent of 0 equals one you then multiply that one with -2 / -4,... the same way any number divided that number is one except zero yada yada yada...

If its (6ab - 2b^2) / (12ab - 4b^2) pull out the common multiples from the numerator and dominator also .5b^2 and 1 don't work

Review this: I plan to solve the problem using the fact that the work done by gravity on the gas will equal the change in internal energy. I reason this because Q = u + W The process is adiabatic so u = -w does that work?

Im getting 66.34 kg can someone confirm this

No its right out of a physics book! Its a thermodynamics problem

An insulated cylinder of cross-sectional area .010m2 contains a monatomic ideal gas at T= 280 K. The system is in a vacuum chamber. Initally the gas supports the piston at a height of .20m. Sand is slowly placed onto the piston. When 10 kg of sand has been added, the piston has fallen .05m. How...
