The question looks easy but I do not know how to get the final answer. No examples like it or any other questions in the book. Could someone please show me the working out to get it??

e) (1 / √x-1) + (√x-1)

Answer is: x (x-1) ^(-1/2)

Thanks

Depends on the difficulty of the exam but getting 45/80 in the past 2 years exams would get you a B

Would 45/80 on exam 2 generally be a decent score to get for an average methods student?
