Question

can anybody tell me if B is the correct answer?

Answer 1

Why would you say B?

Answer 2

Nope. try again :) @RH

Answer 3

D?

Answer 4

@genius12 why don't you let him explain his reasoning?

Answer 5

her*

Answer 6

Oops sorry :(

Answer 7

@skullpatrol lol.

And secondly, the way this is working right now is she tries to figure the answer and asks whether it's correct or not. If it's not, I say it isn't and she tries again until she gets it.

Get it?

Answer 8

That is called "GUESSING"!!!

Answer 9

@RH not D either. try again =P

Answer 10

@skullpatrol she isn't guessing....

Answer 11

I have no idea then how to solve it :(

Answer 12

So you guessed?

Answer 13

@skullpatrol if she was guessing she would've kept guessing instead of giving up lol =P

Answer 14

If she cannot tell how she got it, then it's guessing. She is not going to get better.
Disastrous to guess during an exam!

Answer 15

All I am saying is let the asker explain :-)

Answer 16

Ok then. Now observe that \(\bf 1 = i^4\). So now we re-write the problem as:\[\bf \frac{ 6 }{ 5i }=\frac{ 6 }{ 5 } \times \frac{ 1 }{ i }=\frac{ 6 }{ 5 } \times \frac{ i^4 }{ i }=\frac{ 6 }{ 5 } \times i^3=\frac{ 6 }{ 5 }(i^2)i=\frac{ 6 }{ 5 }(-1)i=\frac{ -6i }{ 5 }\]

Answer 17

@RH get it?

Answer 18

yeah well it would be nice if someone would want to help me? not fight like this...

Answer 19

@RH
One of the best ways to learn is by first hand experience. If you don't get it, you can always ask for explanation. If you get it (with the right reasons), it will give you confidence for other problems.

Someone explaining it to you without any effort on your part will benefit the person who explained, not so much you, unfortunately. :)

Answer 20

I understand it ! And that is the way I solved it I just didn't use the minus sign in the end. so thanks @genius12 for clearing that up :)
