Thank you for the opportunity to help you with your question!

2mn/4m^4n^-3

=  mn /2 m^4n^-3

= m *m^ -4 * n / 2 n^-3                     ( because 1 / m^4 = m^ -4)

= m^(1+ -4) * n / 2 n^-3                      (because m^ 1 * m^-4 = m^(1+ -4)

= m^(-3) * n / 2 n^-3

= m^(-3) * n *n^ 3 / 2                       ( because 1 / n^ -3= n^ 3)

= m^(-3) * n ^(1+ 3 ) / 2                   (because n*n^3 = n^(1+3)

= m^-3 * n ^ 4 / 2 .........................................ANSWER

= n ^ 4 / 2  m^3 .........................................ANSWER

= m^-3 * n ^ 4 / 2

= n ^ 4 / 2  m^3 .

both are same ...you can select the answer from your choices

Please let me know if you need any clarification. I'm always happy to answer your questions.....thank you
