Multiple choice Simplify, expressing your answer with positive indices: (m3n-2)-7÷(m-5n3)4 m2n2 m21n2 m8n5 n2/m Reveal answer Fill a bubble to check yourself D Correct answer Explanation (m^3 * n^-2)^-7 / (m^-5 * n^3)^4 = (m^-21 * n^14) / (m^-20 * n^12) = m^(-21 - (-20)) * n^(14 - 12) = m^-1 * n^2 = n^2 / m.
