You are asking for help. What kind of help do you need. It certainly won't help for someone else to do the problems for you. You learn mathematics by doing mathematics, not by watching someone ese do it!
To know what kind of help you need, we need to see what you do understand about these problems, what you can do, and where you are stuck. And to know that, we need to see what you have done on them yourself.
