Answer 2

Answer:

Step-by-step explanation:

I am assuming that you meant the following:

 12b^7

------------

  4b^5

Note that " ^ " is the proper symbol for exponentiation, and " * " for multiplication.

12/4 = 3 and b^7 / b^5 = b^2.  Thus,

 12b^7

------------ = 3b^2 (or, better yet, 3b²).

  4b^5
