## Brandon Lam Group Title Dividing Radical ∛(a^3+b^3 )/∛(a+b) 3 years ago 3 years ago

1. lokisan

Radicals are just expressions for powers, so you can use power laws to turn your orginal expression into:$\left( \frac{a^3+b^3}{a+b} \right)^{1/3}$

2. lokisan

You then use polynomial or synthetic division to divide that expression.

3. lokisan

The fraction is$a^2-ab+b^2$so your expression will become,$\sqrt[3]{a^2-ab+b^2}$

4. Brandon Lam

How you division

5. lokisan

Hmm, it's a bit difficult to explain on this site. I'll see if I can find a link with a clip.

9. lokisan

Sorry, I'm sure what you want?

10. lokisan

You still want me to do the division?

11. Brandon Lam

division like this: a+b:〖 a〗^3+ b^3

12. Brandon Lam

you just write eqution and I know how to division

13. lokisan

okay

14. Brandon Lam

I just want to know what number division by what number

15. lokisan

a+b | a^3 + b^3

16. lokisan

The denominator appears on the LHS, the numerator on the RHS.
