Dividing Radical ∛(a^3+b^3 )/∛(a+b)
Radicals are just expressions for powers, so you can use power laws to turn your orginal expression into:\[\left( \frac{a^3+b^3}{a+b} \right)^{1/3}\]
You then use polynomial or synthetic division to divide that expression.
The fraction is\[a^2-ab+b^2\]so your expression will become,\[\sqrt[3]{a^2-ab+b^2}\]
How you division
Hmm, it's a bit difficult to explain on this site. I'll see if I can find a link with a clip.

It's not a hard thing to do - you'll pick it up quickly.
can you tye wgat number I need division
Sorry, I'm sure what you want?
You still want me to do the division?
division like this: a+b:〖 a〗^3+ b^3
you just write eqution and I know how to division
okay
I just want to know what number division by what number
a+b | a^3 + b^3
The denominator appears on the LHS, the numerator on the RHS.
let my try,thank
You're welcome
Can any of u help me how to draw the graph
The graph of what?
thank, I can solve now
No probs. Become a fan :)
