## anonymous 3 years ago Radicals problem?

1. anonymous

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

2. anonymous

Simplify.

3. anonymous

can u use calculator ?

4. anonymous

No

5. anonymous

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

6. anonymous

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

7. anonymous

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

8. anonymous

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. anonymous

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! (:
