Solution for e^1.2x=4/x equation: 


D( x )

x = 0

x = 0

x = 0

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

e^1.2*x = 4/x // - 4/x

e^1.2*x-(4/x) = 0

e^1.2*x-4*x^-1 = 0

e^1.2*x-4*x^-1 = 0

x^-1*(e^1.2*x^2-4) = 0

e^1.2*x^2 = 4 // : e^1.2

x^2 = 4/(e^1.2)

x^2 = 4/(e^1.2) // ^ 1/2

abs(x) = 2/(e^0.6)

x = 2/(e^0.6) or x = -(2/(e^0.6))

1/x = 0

1*x^-1 = 0 // : 1

x^-1 = 0

x należy do O

x in { 2/(e^0.6), -(2/(e^0.6)) }
