Solution for 5/m^3+2/4m equation: 


D( m )

m^3 = 0

m^3 = 0

m^3 = 0

1*m^3 = 0 // : 1

m^3 = 0

m = 0

m in (-oo:0) U (0:+oo)

(2/4)*m+5/(m^3) = 0

1/2*m+5*m^-3 = 0

m*(5*m^-4+1/2) = 0

5*m^-4 = -1/2 // : 5

m^-4 = -1/10

-4 < 0

1/(m^4) = -1/10 // * m^4

1 = -1/10*m^4 // : -1/10

-10 = m^4

m = 0

m = 0

m in { 0} 

m belongs to the empty set
