5. theDevonator

that is how it looks on paper

|dw:1356707913752:dw|

7. theDevonator

Yes.....100%

how am i wrong?

my reasoning isn't wrong either.....by the way i didnt understand urs @ayushprasad

I'm using imaginary numbers.

14. theDevonator

right because, i do remeber that the square root of -1 is imaginary

No it isn't.

The square root isn't HALF that number, that's dividing by 2...

It's the number that can multiplied by itself to get that number.

ya sorry @ayushprasad ........sqaure root is twice a number which gives u -10 so.....square root is that number raised to half

so my working is correct

well i admit i was wrong when i said that square root is HALF a number.....its the number RAISED TO THE POWER of HALF....sorry

is THAT wrong @ayushprasad ?........... i dont think so

@theDevonator ........? what do u think?
