Question

How would I multiply this without a calculator?

2sqrt(2)/sqrt(17)*(sqrt(17)/sqrt(17))

Answer 1

\[\frac{2\sqrt{2}}{\sqrt{17}} * \frac{\sqrt{17}}{\sqrt{17}}\]

Answer 2

write with brackets....its not clear..

Answer 3

We have
\[\frac{2\sqrt 2}{\sqrt{17}}* \frac{\sqrt{17}}{\sqrt{17}}\]

Answer 4

2sqrt(2)/sqrt(17) = 2sqrt34/ 17
(sqrt(17)/sqrt(17)) = 1
result is 2sqrt34/17

Answer 5

So...

\[\frac{2\sqrt 2}{\sqrt{17}}* \frac{\sqrt{17}}{\sqrt{17}} = \frac{2\sqrt{34}}{17}\]

is that what your saying?

Answer 6

Yeah, you're correct

Answer 7

yup

Answer 8

So you just multiply under the radical you don't multiply outside by the 2 also.

Answer 9
