3. anonymous

here.. try this site it helps alot https://mathway.com/

4. anonymous

let me kno if you get the answer

5. karatechopper

well first what do you get when you multiply the radicals?

6. anonymous

8

7. karatechopper

how about the x's?

8. anonymous

x^2?

9. karatechopper

when you have the same base you add the exponents.. so x^2(x) x^(2+1) what do you get?

10. anonymous

x^3

11. karatechopper

great put it all together and we know it's $\sqrt{8x ^{3}}$ right?

12. anonymous

yes.

13. karatechopper

okay, now from here. how do we simplify radicals?

14. anonymous

c?

15. karatechopper

uhmnot quite

16. anonymous

okay..no. /.\

17. karatechopper

we take everything in pairs of 2 out. So let's expand this variable. $\sqrt{2\times2\times2\times x \times x \times x}$ so what pairs can we take out?

18. anonymous

a pair of 2's and a pair or x's.

19. anonymous

so 2x sqrt 2x

20. karatechopper

yes!
