$3.$ Both the MIPS and the ARM$7$ processors use addresses that are $32-$bit unsigned integers.

Assume the MIPS processor and the ARM$7$ processor must each execute a beq instruction

located in memory at address $0$x$400$B$5678.$

a$)(5)$ What is the highest address to which this MIPS beq instruction can branch?

Highest address $=0$x$\_\_\_\_\_\_\_$

b$)(5)$ What is the highest address to which this ARM$7$ beq instruction can branch?

Highest address $=0$x$\_$
