$(10$ pts each$)$ Write MIPS$-$Assembly programs to implement the following mathematical

expressions $[$use only the "LOOP approach", and the lecture notes$]$:

$($a$){\displaystyle \underset{a=1}{\overset{3}{}}}[a^2]$

$($b$){\displaystyle \underset{a=1}{\overset{3}{}}}[a^2+1]$

$($c$){\displaystyle \underset{a=1}{\overset{3}{}}}[3a^2+2a+1]$

Store the results ONLY in REGISTER: $$s7$

Provide a screenshot with decimal result $($REGISTERS$-$FILE$).$

At the end of the problem clearly state the result $($decimal$)$
