Write four MIPS$$Assembly programs to implement the following mathematical ex$-$

pressions $($use only the $$LOOP approach$$: see lecture notes$)$:

$($a$)(25$ pts$)$ :

$2$

X

a$=1$

$[$a$]$

$($b$)(25$ pts$)$ :

$2$

X

a$=1$

$[$a$2]$

$($c$)(25$ pts$)$ :

$2$

X

b$=1$

$2$

X

a$=1$

$[$a $+$ b$]$
