Question

sorry @Hero, but can you help again?

Answer 1

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

Answer 2

@Bladerunner1122, there's more to it than you think.

Answer 3

No, it's not that simple unfortunately

Answer 4

oh?

Answer 5

Enlighten me.

Answer 6

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.

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

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

Answer 11

@AriPotta, that's not what I got when I multiplied

Answer 12

Oh darn it. I'm totally wrong. xD

Answer 13

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

Answer 14

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

Answer 15

yes

Answer 16

mmk. thanks guys :)

Answer 17

Sorry for the confusion. xD
