4. Our usual number system is base 10, because it strings together the digits 0-9 to form any whole number (there is a l's place, a 10's place, a 10-squared's place, etc). Hexadecimal numbers are written in base 16. This means they string together the digits 0-9 and the letters A - F to form any whole number (there is a l's place, a 16's place, a 16-squared's place, etc). For example, BD3C8 and 305A2 are two different 5-digit hexadecimal numbers. How many 9-digit hexadecimal numbers are there that have exactly 4 zeroes. (Note: Hexadecimal numbers, like our normal base 10 numbers, cannot start with a 0).
