\textit{Q.E.D}  \\\\  This implies that $2^n+3^n+4^n = O(5^n)$ because for $n\geq c$, $2^n+3^n+4^n$ is bounded by and never exceeds $5^n$. Therefore, $2^n+3^n+4^n = O(5^n)$.  To submit the homework, you need to upload the pdf file into ilearn by 8AM on Tuesday,  January 21, and turn-in a paper copy in class.  Remember that only {\LaTeX} papers are accepted. Also,  remember to turn in your signed academic integrity statement.  (You can scan it and submit via ilearn, turn it in in class, or  slip it under my office door.)
