Answer 1

\[-\frac{ 2 }{ 4 }=\frac{ 2 }{ \sqrt{2} }\]like this?

Answer 2

-2/4 * 2/sqrt(2)

Answer 3

\[\frac{ 2 }{ 4 }\times \frac{ 2 }{ \sqrt{2} }\]

Answer 4

Yes

Answer 5

alrite

Answer 6

I'm sorry if I got the terms wrong. This isn't my strongest point in math, and I'm struggling with this concept - moreso since I'm currently working on the unit circle

Answer 7

So an explanation would really be helpful

Answer 8

it's okay..
step 1:simlifyit it until it is in simplest form\[-\frac{ 2 }{ 4 }\times \frac{ 2 }{ \sqrt{2} }\]

Answer 9

*simplify

Answer 10

How do I simplify the 2 and the square root of 2? or am i completely off .-.

Answer 11

\[-\frac{ 1\cancel{2} }{ 2\cancel{4} }\times \frac{ 2 }{ \sqrt{2} }\]

Answer 12

okay…

Answer 13

So 1/sqrt(2) ?

Answer 14

then,s\[-\frac{ 1 }{ 1\cancel{2} }\times \frac{ 1\cancel{2} }{ \sqrt{2} }\]

Answer 15

Okay, I see where that comes from! Cool!

Answer 16

it should hv the negative sign.. :)

Answer 17

*-1/sqrt(2) … sorry, figured haha

Answer 18

So the only option I see for the answer is -sqrt (2)

Answer 19

Is there another step to that?

Answer 20

yep

Answer 21

hint:\[a^-{\frac{ 1 }{ 2 }}=\frac{ 1 }{ a^{\frac{ 1 }{ 2 }} }\]

Answer 22

so would the -1 / sqrt(2) become -sqrt(2) according to that then?

Answer 23

or am i totally off

Answer 24

lt will be like this
\[-\frac{ 1 }{ \sqrt{2} }\]\[=\frac{ 1 }{ 2^{\frac{ 1 }{ 2 }} }\]

Answer 25

yep,that's right!

Answer 26
