.

The rule is simple:

    - where you see the third degree, is cubic;

    - where you see logarithm ( log, in short ), is logarithmic;

    - where you see degree of "e", is the exponent.

It is the rule.


The rest depends on your watchfulness/observancy.

By the way, can you explain, why the last expression and the one before the last are identical ?

Did you include two identical expressions in order for we, the tutors, better memorized the repeating items ?
