Answer:

Explanation:
For this case we know the following info :
represent the initial volume
represent the final volume
We know that the pressure and volume are related with the following expression:

Where a is a constant given 
And we need to calculate the work associated to this process.
We have a compression, and by definition the work is defined with the following general expression:

If we replace the expression for P we got:

If we integrate we got:

Using the fundamental theorem of calculus we have:

And replacing the values we got:
