v=4/3x3.14x11.74

Solution for v=4/3x3.14x11.74 equation:

D( x )

x < 0

x < 0

x in <0:+oo)

v = (4/3)*x^3.14*x^11.74 // - (4/3)*x^3.14*x^11.74

v-((4/3)*x^3.14*x^11.74) = 0

v+(-4/3)*x^14.88 = 0

-4/3*x^14.88 = -v // : -4/3

x^14.88 = 3/4*v

x^14 = (3/4*v)^(1/0.88) // ^ 1/14

abs(x) = (3/4)^0.0811688298051948*v^0.0811688298051948

x = (3/4)^0.0811688298051948*v^0.0811688298051948 or x = -((3/4)^0.0811688298051948*v^0.0811688298051948)

x in { (3/4)^0.0811688298051948*v^0.0811688298051948, -((3/4)^0.0811688298051948*v^0.0811688298051948) }
