I tried Hero999, but it would not upload. Anyways, sorry for the trouble.

Factorise:

(2 a square b square + 2 b square c square + 2 a square c square - a raised to the power of 4 - b raised to the power of 4 - c raised to the power of 4) / 16. The whole expression is under root.

Sorry, because the sum is in words.

For some reason the Latex on this form requires an variable/number followed by an equals sign.

For example, you can have:
$f_0 = \frac{1}{2 \pi sqrt{LC}}$
or:
$81 \times 10^6 = \frac{1}{2 \pi sqrt{82 \times 10^{-9} \times 47 \times 10^{-12}}}$
But you can't have:
$\frac{1}{2 \pi sqrt{LC}}$
or even something simple like:
$a+b$

I suppose a + b doesn't make much sense on its own.

I do not not understand what you express. However, that is beside the point. Could you please help my with me problem. I do not seem to get it.

I meant that Latex on this forum won't let you have:
a + b

you need to have:
c = a + b

This means that what you want to do won't work unless you have an = sign somewhere in-between some numbers or variables.

$\lim_{h\to\0} \left( \frac{f(x+h)-f(x)}{h}\right)$

$P = F_{{||}}v$

$m_{{1}}v_{{1}} = m_{{1}}v_{{2}} + m_{{2}}v_{{3}}$

$z = {{{{{{{x^y}^a}^}^c}^}^}^d}$

Edit: thanks eng1

Like this? $b = x^{y^2}$

Use curly brackets to surrond expressions, like y^2.
