Question

Simplify and write the answer using only positive exponents.
-35 x^3 y^3/28 x^-2 y^7

Answer 1

[-5x^(3+2)]/[4y^(7-3)]

35 and 28 have a common factor of 7 that cancels out.
a negative exponent like 1/x^-2 becomes x^2 and then you just add. And 7 is bigger than3 so take it to the bottom and subtract.

Answer 2

-5x^5/4y^4
