The reciprocal changes the sign of exponents
%283m%5E-7%29%2Fm%5E-4 = 3%2F%28m%5E%28-4%2B7%29%29 = 3%2Fm%5E3

It critically depends on what do you mean in your post:   3m%5E%28-7%29   or   %283m%29%5E%28-7%29.


As you pronounce your words,  they do not make difference between these cases.


Wording formulas do not work in Math: only mathematical symbols works.

Even do not try to express math formulas in words:  in  99.999%  cases your wording will be  INCORRECT/inADEQUATE.


During thousand years of intensive brainwork,  the humanity developed the language of Mathematical formulas to express mathematical ideas.


Do not neglect it . . .
