Question: An RSA cipher has the public key pq=65 and e=7. What is the encrypted value of 3 integers a,b and c. $$ \begin{align*} &M={ C }^{ d }mod\quad pq,\quad M\quad <\quad pq,\quad and\quad \\ &C={ M }^{ e }\\ &by\quad substitution,\\ &{ C }^{ d }mod\quad pq\quad =\quad ({ M }^{ e }\quad mod\quad pq{ ) }^{ d }mod\quad pq \end{align*} $$
I have tried to research this question and found an overwhelming amount of information am not I am sure what my first steps should be, what the middle part is and how to end.
