Answer 1

HI
and no

Answer 2

How would you solve it?

Answer 3

compute the distance for each
it is not that hard

Answer 4

you need the distance formula

Answer 5

I'm not saying it's hard, I was just asking if there was a simpler way.

Answer 6

no i don't think it is obvious without doing that

Answer 7

Okay, thanks ^_^

Answer 8

\[\sqrt{4^2+5^2}\] for the first pair\[\sqrt{3^2+6^2}\] for the second
actually you can ignore the square roots if you just want to compare the numbers
