How many hexadecimal digits are required to represent the binary string '1011 0101 1001 0011'?

Explanation:
The key idea is that each hex digit encodes 4 bits. The binary string shown is arranged in four 4-bit groups: 1011, 0101, 1001, 0011. Since there are four groups, you need four hex digits to represent it. If you convert each group to hex, you get B, 5, 9, 3, so the hex representation is B593, which confirms there are four digits.
