Please do not give solution in image format thanku 6. Represent the decimal number -86 in 8-bit binary number using the following representation methods: a) Two’s complement b) Signed-magnitude   7. What decimal value does the 8-bit binary number 10010010 have if: a) it is on a computer using signed-magnitude representation? b) it is on a computer using two’s complement representation? c) it is on a computer using excess-M representation?   8. Assume we are using the simple model for floating-point representation discussed in the class (the representation uses a 14-bit format, 5 bits for the exponent with an Excess-M, a significand of 8 bits, and a single sign bit for the number and uses implied 1 representation):  Convert -23.275 to the floating-point binary representation.
