Question

Well, I'm back with some more square roots.

Simplify: 8√ x √5 x √2 x √20

The x's are multiplication signs.

Answer 1

sqrt8 can be written as sqrt(4 x 2)

Answer 2

\[\sqrt{8}=\sqrt{4*2}=2\sqrt{2}\]

Answer 3

Oh, jeez.

Answer 4

I'm gonna have to break them all down, huh?

Answer 5

break down the sqrt 20 as well
\[\sqrt{20}=\sqrt{4*5}=2\sqrt{5}\]

Answer 6

no just the sqrt8 and sqrt20
the others can't be broken down any further

Answer 7

P.S. you can do a √ by holding alt on your keyboard, then typing 251, then let go of Alt.

Answer 8

(sqrt) is annoying. ._.

Answer 9

Oh btw, type 251 on your numpad. not the ones above your keyboard. But anyways...

Answer 10

I guess you can keep using sqrt. If you must. lol.

Answer 11

dont have a numpad, its a small laptop...notebook thing

Answer 12

Kay. Anyways, moving on then.

Answer 13

anyway. can you figure it out from there ^^^

Answer 14

Let me try real quick....

Answer 15

Nope. I suck at simplifying square roots ;_;.

Answer 16

oops!!! I misread the question

Answer 17

just multiply everything together

Answer 18

.-.

Answer 19

then my original guess of √35 would be correct, yeah?

Answer 20

that IS aa multiplication between each sqrt right?

Answer 21

Yes it is.

Answer 22

\[=\sqrt{8*2*5*20}\]\[\sqrt{8}*\sqrt{2}*\sqrt{5}*\sqrt{20}\]

Answer 23

sorry, the 1st line was supposed to go underneath the 2nd one

Answer 24

SO √35, right?

Answer 25

That's the answer? It's one of my options. It's kinda an online quiz.

Answer 26

That's what I'm doing.

Answer 27

no, 8 x 2 x 5 x 20 = 1600

sqrt1600 = 40

Answer 28

Wow. well then. √40 is also an option.

Answer 29

So I'll go with that. Thanks....

Answer 30

no, just 40

Answer 31

Yeah. there's 40 and √40.

Answer 32

just 40 :)

Answer 33

Can't wait until square roots is over. I hate square roots now.

Wasting hours of my time with this damned stuff.

Answer 34

Very tricky and annoying.

Answer 35

Well, I PERHAPS got the hang of square roots. I'm not even sure. Probably in another quiz I'll be thrown a problem that I get stuck on, and I'll probably have to come back to OpenStudy again to get help for it.... But anyways, thanks again. :/

Answer 36

np

Answer 37

Square Roots seemed simple at first... I was wrong lol.

Answer 38

well, ok bye :)
