If possible, briefly explain so I can complete problems like this in the future. Thanks! 9. Express x*K using on only the specified number of operations: (a) K = 7, using 1 shift and 1 Add/Sub (b) K = -13, using the fewest possible shifts and Add/Subs 10. Write C expressions that evaluate to 1 when the following conditions are true and to 0 when they are false. Assume x is of type int. (a) Any bit of x equals 1. (b) Any bit of x equals 0. (c) Any bit in the least significant byte of x equals 1. 11. Convert between binary and decimal representations: (a) 11.475 to binary (b) Binary 110000011001111 to hexadecimal (c) Binary 101.1111 to decimal 12. Show the result of rounding to the nearest 1/8 according to the round-to-even rule: (a) 11.0001 (b) 11.0010
