Can you help me find out what c is?

 "    " .

________________________________

Step-by-step explanation:

________________________________

The question states:  "Can [you] help [me] find out what "c" is ? " .

________

       "Can [you] help [me] find out what "c" is ? " .

 →  We are to "Part C" —within the "attached image" given:

________

 →   " ÷ " ;  can be written in the form of:  " " .

 →     Express z  in terms of m and n .

________

Note: Rewrite:  " " ;   and:  " " ;   as powers of "" ;

  →  with "" being the "base number" .

________

Let us start with:  " " .

Note that the number:  " " ;

     →   since " " ;  has 3 (three) zeros after the "1" digit;

     → & since:  " " .

So:  →   .

Now, let's simplify further.

Note the "multiplication property" of exponents:

    →   .

As such:  →  

________

Likewise:  We can continue by rewriting our other term:

    →  " " ;  as a power of "" ;

             with "" being the "base number."

Note that the number:  " " ;

     →   since " " ;  has 2 (two) zeros after the "1" digit;

     →  & since:  " " .

So:

     →   .

Now, let's simplify further.

________

Again:  As aforementioned:

Note the "multiplication property" of exponents:

    →   .

As such:

     →   .

________

Now, refer to the original problem:

     →  "  ÷    "  ;  

Rewrite this expression by substituting:

    →   " " ;  ←  [for:  " ."] ;  And:

    →   " " ;   ←  [for:  " ."] ;

As follows:

    →  "  ÷   "  .

________

Now:  Note the following "division property" of exponents:

________

    →   ;  

________

As such; let's rewrite our expression; and simplify—by plugging in our values into the "equation/formula" directly above; in which:

________

→  " " [in the aforementioned formula] is:   " " .

→  " " [the 'exponent' in the aforementioned formula] is:                                                                                                    

                                                                          " " .

→  " " [the 'exponent' in the aforementioned formula is:

                                                                          " " .

→  " " [in the aforementioned formula] is:  " " ;

→  " "  [in the aforementioned formula] is:  " " .

________

  →  Let's plug in our values;  and then "simplify" ; as follows:

________

→   ? ;  

                .

→      .

________

So:  →   " " ;

    ↔   " " .

         →  " " .
