Best ResponseYou've already chosen the best response.0Technically you're not completely wrong, but it's nicer to multiply by sqrt(2)/sqrt(2) to get the radical out of the denominator.

Best ResponseYou've already chosen the best response.1The fraction is not in simplest form. You have to rationalize like what @Kainui is suggesting.

Best ResponseYou've already chosen the best response.0You can multiply by sqrt(2)/sqrt(2) since it equals 1, and you can multiply anything by 1 without changing it.

Best ResponseYou've already chosen the best response.1\[7 \times \sqrt{2} = 7\sqrt{2}\] \[\sqrt{2} \times \sqrt{2} = 2\]

Best ResponseYou've already chosen the best response.2Mhmm... I got √(2x7x7) / 2 = 7√(2) / 2
