<p>Taken together, OP is asking primarily about how to do their homework. It's a self-study question.</p>
<p>Please note that it's not true that asking about how to solve a homework/exam problem is off-topic. Instead, someone asking for help with a self-study problem must also make a good-faith effort to show how they tried to solve the problem: what they know, what they've tried, and where they are stuck. Only questions that do not provide this information are closed. The lack of demonstrated effort is the reason that this question was closed.</p>
