How do you approach problems that are seemingly ridiculous?

[shook1]

<p>just get rid of the 400 and use 2^4 instead…</p>

<p>2^4=16 16/10 has a remainder of 6</p>

<p>when you are faced with problems like this, you can almost always reduce or make the question easier. obviously the SAT doesn’t expect anyone to be able to do 2^400</p>
