Can someone please check my answers below for accurateness? The instructions are: Differentiate and simplify.
O.K. Bold the wrong answers or let me know which ones I should double check and fix. Thanks for your help and I really appreciate it because there are no answers to these questions in the back of the book, so I need to know if they are correct. Thank you once again!
On number 2, I believe you copied the question incorrectly.
Many of the problems can be simplified by foiling and adding terms (#1, 2 for example)
#2 is completly wrong
#3 has the wrong coefficent for the x^(2/3) term
#7 looks suspicious
#7 is correctly differentiated and simplified
