Simplify each expression. use positive exponents.
1. m3n-6p0
2. a^4b^-3/ab^-2
3. (x^-2y^-4x^3) -2

To simplify each expression, we need to group all the terms that have the same bases and flock them if necessary to one side. One rule that applies is that negative exponents goes to the other side in order to be positive.

1. m3n-6p0 ; p0 =1 , so, m3/n6
2. a^4b^-3/ab^-2  = a^4a-1 / b^-2b^3 = a^3/b
3. (x^-2y^-4x^3) -2 = (x^-2x^3 y^-4 )^-2 = (x/y^4)^-2 = y^16/x^2

The correct answer is 10%
