Question

4. What is the simplest form of the expression?

Answer 1

what expression

Answer 2

\[\frac{ \sqrt{3}-{\sqrt{6}} }{ \sqrt{3} +{\sqrt{6}}}\]

Answer 3

sorry idk bye

Answer 4

A.\[\frac{ -1 - 2\sqrt{18} }{ 3 }\]
B.\[\frac{ -3 - 2 \sqrt{18} }{ 9 }\]
C,\[-3+2\sqrt{2}\]
D.\[9-2\sqrt{18}\]

Answer 5

\[\frac{ \sqrt{3}-{\sqrt{6}} }{ \sqrt{3} +{\sqrt{6}}}\times \frac{ \sqrt{3}-{\sqrt{6}} }{ \sqrt{3} -{\sqrt{6}}}\] is a start

Answer 6

the denominator is \(3-6=-3\) and the numerator is
\[(\sqrt3-\sqrt6)(\sqrt3-\sqrt6)\]\[=3-2\sqrt{18}+6\]
\[=9-2\sqrt{18}\]
\[=9-6\sqrt{2}\]

Answer 7

final answer is got by reducing
\[\frac{9-6\sqrt2}{-3}\]

Answer 8

thats not one of my answer choises

Answer 9

the answer is correct - just need to be simplified to get your choice.

\[\frac{ 9 }{ -3 } + \frac{ -6\sqrt{2} }{-3 }\]

= \[-3 + 2\sqrt{2}\]
which is choice C
