Which is the hex representation of binary 1011 0101 1001 0011?

Explanation:
Hex numbers are written by grouping binary into 4-bit chunks, since each hex digit represents one 4-bit nibble. For the 16-bit string 1011 0101 1001 0011, the chunks are 1011, 0101, 1001, and 0011. Converting those to hex gives B, 5, 9, and 3, respectively, so the hex representation is B593. The 0x prefix is just another way to denote hex in many languages, so 0xB593 would mean the same value, but the digits themselves are B593.
