1. ## Furd

My daughter (year 10) has come home wanting help with SURD's - she needs to simply 3 x sqrt 6 x sqrt 2

I have never heard of a FURD and can't find a descritption - can anyone help please?

2. First of all it seems you want to say Surd

Read this A-level Mathematics/OCR/C1/Indices and Surds - Wikibooks, collection of open-content textbooks

$
3\times \sqrt{6} \times \sqrt{2}
$

$
=3 \times \sqrt{2\times 3} \times \sqrt{2}
$

$
=6\times \sqrt{3}
$

If you wondering how to get from there to

$
=6 \times \sqrt{3}
$

$
\sqrt{2}\times \sqrt{2} = 2
$

Therefore we get:

$
=3 \times 2\sqrt{3}
$

$
=6\sqrt{3}
$

4. at least he didn't say turd, oops, I did , sry
