Question 127833: I know that it said in the book it involved expressions. This is question 21. off of Lesson 8.2 Practice C worksheet.
-48x^-6y^4/52x^9y^-2
I know how to solve part of it but the fraction bar confuses me with switching it up and down.
I will really appreciate a tutors help.

%28-48%29x%5E-6y%5E4%2F52x%5E9y%5E-2

If you have a negative exponent on a variable, change the sign and move the variable from the numerator to the denominator or vice versa, because a%28-n%29=1%2Fa%5En

So:
%28-48%29y%5E4%2Ay%5E2%2F52x%5E9x%5E6

Then sum the exponents on like variables, because a%5Em%2Aa%5En=a%5E%28mn%29

%28-48%29y%5E6%2F52x%5E15

Then you can get rid of a common factor of 4 in the coefficients

%28-12%29y%5E6%2F13x%5E15
