## vivalakoda 3 years ago Radicals problem?

1. vivalakoda

$\sqrt{5}(10-4\sqrt{2})$

2. vivalakoda

Simplify.

3. Living_dreams

can u use calculator ?

4. vivalakoda

No

5. CliffSedge

Doesn't seem to be much to do besides distributing.

6. Living_dreams

[2(5\sqrt{5}-2\sqrt{10})\]

7. joodster

|dw:1353339739638:dw| Just use simple distribution.

8. vivalakoda

That's what I originally thought as well, but my answer choices are: a. 14 b. 15√2 c. 5√2 - 4√10 d. None of the above

9. joodster

Then it's d. None of the above because I can't think how else the problem can be simplified lol. The only other way the answer can be rewritten is$-2\sqrt{5}(2\sqrt{2}-5)$

Meh, okay. Thank-you!

You're welcome! (:
