Evaluate only using positive exponents
\n" ); document.write( "(2m)^−2 * n^5 / −m^4 * n^−3
\n" ); document.write( "-----
\n" ); document.write( "If I assume you did not just drop the parentheses
\n" ); document.write( "in your problem, and if you are to follow the PEMDAS rule
\n" ); document.write( "of operation, you get::
\n" ); document.write( "(1/(4m^2)*(1/n^3)
\n" ); document.write( "----
\n" ); document.write( "= n^5/[(4m^2*(-m^4)(n^3)]
\n" ); document.write( "----
\n" ); document.write( "= n^5/[-4m^6*n^5]
\n" ); document.write( "---
\n" ); document.write( "= 1/[-4m^6]
\n" ); document.write( "----
\n" ); document.write( "Comment:: Using parentheses (to clarify) in your post
\n" ); document.write( "would help avoid much confusion. One of your responders
\n" ); document.write( "assumes your problem is a fraction ((2m)^-2 *n^5)/(-m^4*n^-3).
\n" ); document.write( "I did not.
