    Your answer is correct.
     
  4. Your answer looks correct to me, I think it's a book typo.

    The only i will say is that when you have integrate 1/x you write x^0 evaluate between 1 and 4, but then you evaluate it between natural logarithm. You shouldn't write x^0. The integral of 1/x is just ln(x).
     
  5. Great. Thanks guys.
