( ∛3x+5 ) + 4 = 0

Algebra 2  Bosnian, Monday, May 7, 2012 at 4:54am
third root ( 3 x ) + 5 + 4 = 0
third root ( 3 x ) + 9 = 0
third root ( 3 x ) =  9
93 x =  9 ^ 3
3 x =  729 Divide both sides by 3
x =  729 / 3
x =  243

If your expression mean :
third root ( 3 x + 5 ) + 4 = 0
then
third root ( 3 x + 5 ) =  4
3 x + 5 =  4 ^ 3
3 x + 5 =  64
3 x =  64  5
3 x =  69 Divide both sides by 3
x =  69 / 3
x =  23
