(1+n/n^2-mn)-(1-m/m^2-mn)*(m+n/m^2n-n^2m)^-1

Question

(1+n/n^2-mn)-(1-m/m^2-mn)*(m+n/m^2n-n^2m)^-1

Answer 1

Упрощение выражений
(m^4*n^4-m*n^4-m^3*n^3+n^3-m^4*n^2+n^2+m^3*n-m^2*n+m*n+m^3)/(-m^3*n^3+n^3+m^3*n)
Разложение на множители
(-m^4*n^3+m*n^3+m^3*n^2-n^2+m^4*n-n-m^3/n-m^3+m^2-m)/(m^3*n^2-n^2-m^3)
