Help needed for equation solving

Okay thanks CPhill !

Frankly, OneDirection, I find this calculator on the website a little clunky for solving equations....

I like WolframAlpha   ........http://www.wolframalpha.com/input/

Just type your equation in the box and hit "Enter"

cymath with free explonation:

Thanks, Solveit for that website reference......I like the "step-by-step solution"  feature......!!!!

I have just done it on the froum calc.  There is not a problem.  The only real solution is 20 

I just entered 

x^3=8000

x^3=8000 = {x=(10*sqrt(3))*i-10, x=-((10*sqrt(3))*i)-10, x=20}

Melody......check out that website that Solveit referenced.....it includes step-by-step solutions  [ you must pay for this in WA ]

I just tried it.......pretty neat.....I'll definitely be adding that to my bookmarks....!!!
