6/sqrt2
ganeshie8 (ganeshie8):
thats right, but the grader will give u 0 marks
OpenStudy (vshiroky):
why?
ganeshie8 (ganeshie8):
\(\huge \sqrt{\frac{36}{2}}\)
\(\huge \sqrt{18}\)
\(\huge \sqrt{9 \times 2}\)
\(\huge 3\sqrt{ 2}\)

genrally, dont leave radicals in the denominator.
ganeshie8 (ganeshie8):
if u simplify ur answer further by rationaliziing the denominator u wud get the same answer
OpenStudy (vshiroky):
even though it says rationalize the denominator
OpenStudy (vshiroky):
ok..
ganeshie8 (ganeshie8):

rationalize the denominator and see wat u get
ganeshie8 (ganeshie8):
to rationalize, u need to multiply top and bottom by sqrt(2) right ?
OpenStudy (vshiroky):
I thought that's what it wanted, but if I go further it's 3sqrt2?
ganeshie8 (ganeshie8):
\(\large \frac{6}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}}\)
\(\large \frac{6\sqrt{2}}{2} \)
\(\large 3 \sqrt{2}\)
ganeshie8 (ganeshie8):
yes, 3sqrt2 is the final ansur

Gotcha.. thank you
ganeshie8 (ganeshie8):
rationalizing denominator means, getting rid of radicals in the denominaotr
ganeshie8 (ganeshie8):
u wlc :)
