Simplify the expression. 12/c^-8d^2

If you're going to write negative exponents, please enclose them inside parentheses:

12 / c^(-8)
                                       12      8d^2
12/c^-8d^2 becomes  -
                                       c^8        1

Here the LCD is c^8, so the above expression becomes:

 12         c^8*d^2       12-(c^8)(d^2)
- =
 c^8          c^8                   c^8

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
