3. Show the representation of -16 (assuming 8-bit registers) using Two's complement. (5 points) 4. Assume we are using the simple model for floating-point representation as given in the book (the representation uses a 14-bit format, 5 bits for the exponent with a bias of 16, a normalized mantissa of 8 bits, and a single sign bit for the number). Show how the computer would represent the numbers 96.5 and -0.75 using this floating-point format. (15 points)
