47/7 = 7. That means that √49 is 7. That makes the answer 7/√2

Technically you're not completely wrong, but it's nicer to multiply by sqrt(2)/sqrt(2) to get the radical out of the denominator.

The fraction is not in simplest form. You have to rationalize like what @Kainui is suggesting.

OH! yeah. but the answer format requires it in.

You can multiply by sqrt(2)/sqrt(2) since it equals 1, and you can multiply anything by 1 without changing it.

I know, but original question has the answer selection has the √2 in the denominator.

\[7 \times \sqrt{2} = 7\sqrt{2}\] \[\sqrt{2} \times \sqrt{2} = 2\]

Mhmm... I got √(2x7x7) / 2 = 7√(2) / 2
