What ideas have you had so far?

I only remember general knownledge

This is not a homework service. You're expected to put forth some effort, at which point we can help you get unstuck. See Rule # 11 here.

I note that you've posted a lot of problems. That's perfectly fine. However, you need to post some effort in each one, and not expect us to simply solve them for you. That's not what this forum is about.

Then go back and review your classnotes or textbook.

To get help you need to show some effort. Show your work and say where you're stuck.
