Answer 1

okay, so all we have to do is FOIL.

Answer 2

you should get: \[50-13\sqrt{2}\]

Answer 3

i did thank you

Answer 4

Rationalize the denominator of

Answer 5

\[(7)(8)+(7)(-3\sqrt{2})+(\sqrt{2})(8)+(\sqrt{2})(-3\sqrt{2})\]
\[56-21\sqrt{2}+8\sqrt{2}-6\]
\[50-13\sqrt{2}\]

Answer 6

Answer 7

\[\sqrt{50}/\sqrt{5}\]

Answer 8

how do u rationalize the denominator

Answer 9

multiply to and bottom of that fraction by
\[\sqrt{5}\]

Answer 10

i am sorry thats wrong

Answer 11

i got \[\sqrt{10}\]

Answer 12

yeah, thats right

Answer 13

i was thinking about something else

Answer 14

or is it 5\[5\sqrt{5}/2\]

Answer 15

no, its is \[\sqrt{10}\]

Answer 16

how about Rationalize the denominator of \[3/\sqrt{2}\]

Answer 17

When we multiply the top and bottom by \[\sqrt{2}\]
we get :
\[(3\sqrt{2})/(2)\]
