Solution for 2u^(2/3)-7^(1/3)-4 equation: 


u in (-oo:+oo)

2*u^(2/3)-7^(1/3)-4 = 0

2*u^(2/3) = 7^(1/3)+4 // : 2

u^(2/3) = (7^(1/3)+4)/2

u^(2/3) = (7^(1/3)+4)/2 // ^ 3

u^2 = ((7^(1/3)+4)^3)/8 // ^ 1/2

abs(u) = ((7^(1/3)+4)^(3/2))/(2*2^(1/2))

u = ((7^(1/3)+4)^(3/2))/(2*2^(1/2)) or u = -(((7^(1/3)+4)^(3/2))/(2*2^(1/2)))

u in { ((7^(1/3)+4)^(3/2))/(2*2^(1/2)), -(((7^(1/3)+4)^(3/2))/(2*2^(1/2))) }
