This question is estimated to take $21$ minutes. This question pertains to the following binary$-$level

MIPS instruction:

$00100000100001011000000000001010$

a$.(3$ points$)$ Convert this instruction to assembly code $($give the MIPS code$).$

b$.(3$ points$)$ What is the sign of this number? Generally speaking, can you determine the sign

of a number at a glance?

c$.(3$ points$)$ The number $0$b$1000000000001010$ is extended to $48$ bits as $0$b$00000000$

$0000000000000000000000001000000000001010.$ If it is correctly extended, calculate

its value. If it incorrectly extended, explain why.
