The "=" sign is read as "equals" or "is equal to", depending on your culture.
(In the latter case, "is equal to" is such a common phrase all through school that it's typically read as one word:
"izziqualtu".)
The "c 2 " could rarely be "c [raised] to the power of 2", but is almost always "c squared" (or "c square").
Thus, "ee equals em see
square[d]"
or "e is equal to
em see square[d]".
