calculations please (no coding)

Consider a septenary (base-7), normalized, floating-point number system, with chopping. Analogous to a bit, a septenary digit is called an sept. Assume that a hypothetical septenary computer uses the following floating-point representation: where sm is the sign of the mantissa and se is the sign of the exponent (0 for positive, 1 for negative), 81, 82, 83 and se are the septs of the mantissa, and en, ez are the septs of the exponent, an integer, and each sept is 0 to 6. Show all your work for all parts. (a) Let p be a real number in the decimal interval (7-4,7"). If we need to represent p in this floating-point system with some p, what is the upper bound on the absolute error of this representation? Your answer should be in decimal. (b) What is the computer representation of the decimal value 0.1 in this system? (c) What is the true absolute error of the computer representation of 0.1 given in (b)? (d) How many distinct, positive, non-zero values can be represented exactly in this com- puter system
