That is what I got that is the best I can do.

Answer 3

that's not any of the answers, thanks for trying though

Answer 4

what are the answers?

Answer 5

\[\frac{ 8\sqrt{2} }{ \sqrt{2} }\]
\[\frac{ 8\sqrt{7} }{ \sqrt{7} }\]
\[\frac{ 16\sqrt{2} }{ \sqrt{2}}\]
\[\frac{ 16\sqrt{7} }{ \sqrt{7}}\]

Answer 6

ummm... I'm getting (8√7)/7

Answer 7

Oh well that changes things. Yeah I'm getting (8√7)/7 too

Answer 8

than I will choose b thanks @jigglypuff314 @Help_PLEASE_18

Answer 9

would you like an explanation of how we got that?

Answer 10

Your welcome :)

Answer 11

yes pls, when I tried this I got A.

Answer 12

√128 = √(64*2) = √64 * √2 = 8√2
so you get (8√2)/√14
but most people don't want roots in the denominator so multiply by (√14/ √14)
so (8√2 * √14)/(√14*√14) = (8√2 * √14)/(14)
= (8√2*√2*√7)/14
= (8 * 2 √7)/14
= 16√7 / 14
= 8√7 / 7


one must have understood that √14 * √14 = 14
and that √2 * √2 = 2
feel free to ask if you still don't understand :)

Answer 13

wow thanks, I understand everything!!:)

Answer 14

my mistake was here:
(8√2 * √14)/(√14*√14) = (8√2 * √14)/(14)

Answer 15

I see :)
well I'm glad I could help :D
