Answer:

Explanation:


(3m^(-1)y^(2))/(m^(-2))-(5m^(2)y^(2))/(x^(2))+(my^(2))/(m^(-1)x^(2))\\\\=3m^(-1-[-2])y^(2) - (5m^(2)y^(2))/(x^(2))+(m^(1-[-1])y^(2))/(x^(2))\\\\=3m^(-1+2)y^(2)-(5m^(2)y^(2))/(x^(2))+(m^(1+1)y^(2))/(x^(2))\\\\=3my^(2)-(5m^(2)y^(2))/(x^(2))+(m^(2)y^(2))/(x^(2))\\\\=3my^(2)-(4m^(2)y^(2))/(x^(2))
