Perform the following number conversions:
A. 0x39A7F8 to binary: 0b0011 1001 1010 0111 1111 1000.
B. binary 1100 1001 0111 1011 to hex: 0xC97B.
C. 0xD5E4C to bin: 0b1101 0101 1110 0100 1100.
D. binary 10 0110 1110 0111 1011 0101 to hex: 0x26E7B5.
Pay attention! In Hex, if the total number of bits is not a multiple of 4, you should make the leftmost group be the one width fewer than 4 bits.
