For this case we have the following expression: (xy ^ -6) / (x ^ -4y ^ 2) By power properties we can rewrite the expression as: (x * x ^ 4) / (y ^ 6 * y ^ 2) Then, for power properties: Same exponents are added: (x ^ (4 + 1)) / (y ^ (6 + 2)) (x ^ 5) / (y ^ 8) Answer: An expression after the negative exponents have been eliminated is: (x ^ 5) / (y ^ 8)
