In computing we often use different numeral systems in different situations. The most commonly used numeral systems are binary, octal, decimal, and hexadecimal, which are bases $2,8,10,$ and $16,$ respectively. It is easy enough to simply use a programmers calculator to convert numbers among these four bases. However, to ensure you really understand how to do this it is instructive to convert a number from one uncommon base to another uncommon base $"$by hand", so to speak, although a calculator may still be useful when doing so$.$

For this question, first determine what the integer C$5$B$3$C$7$A$9\_13($the $\_13$ text means this is a base $13$ number$)$ is in decimal. Next, convert the base $10$ integer to base $9.$

Your answer must be written in the format ddd$...$d$\_10,$ddd$...$d$\_9$ where the d$\text{'}$s represent digits of the base $10$ and base $9$ integers, ${?}_{10}$ at the end of an integer means the integer is written in base $10,$ and $\_9$ at the end means the corresponding integer is expressed in base $9.$ For example, if you determine C$5$B$3$C$7$A$9\_13$ is $2543698$ in decimal and $746823851$ in base $9$ then your answer must be written as $2543698\_10,746823851\_9($note that your response must not contain any spaces because Canvas, unsurprisingly, lacks support for regular expressions that would permit me to specify that the answer can contain one or more spaces$).$
