 * This function will calculate the base of any number that is <11.
 * You can calculate binary, octal quickly with this as well.
 * For example, to calculate binary of number 4 you can run "echo baseX(4, 2);"
 * and for octal of number 10 you can run "echo baseX(10, 8);"
 *
 * @param int $k The number to convert
 * @param int $x The base to convert to
 * @return string The base-x representation of the given number
