What is the second simplified form of these two problems if there is any other way?
3. There are many ways to simplify exponents. Provide two different ways to simplify each of the problems below. Please write all final answers using positive exponents.
problem 1: (-4m^2 n^2)^3 * (2m^3 n)^-1
simplified 1: -(32n^5/m^9)
simplified 2: ?
problem 2: (x^-(1/2) y^3)^-2/ xy^(1/3) * x^2 y^-4
simplified 1: 1/x^2y^(7/2)
simplified 2: ?
