convert (7A3E)16 to binary

Question

could you help me how can I convert (7A3E)16 to binary

Answer 1

This is easy; you have a hexadecimal number (base 16) and it consists of four 4-bit digits. Below are listed the 16 digits and what they are in binary

0 = 0000   1=0001    2=0010    3 = 0011

4 = 0100   5 = 0101  6 = 0110  7 = 0111

8 = 1000   9 = 1001  A = 1010  B = 1011

C = 1100   D = 1101  E = 1110  F = 1111

 

Just copy down each 4-bit version of the 'hex digits' 7A3E, in order and you have your answer (16 bits).
