left click it and hit show source for a better idea of what it looks like

amistre64 · Answer

that source code is called latex and has to be typed into the equation editor, or if you know about the delimiters it can be typed directly into the reply box

amistre64 · Answer

$$F(x) = \left(\frac{1}{(2x - f(x))}\right)^4$$
$$F(x) = \frac{1}{(2x - f(x))^4}$$
$$F(x) = (2x - f(x))^{-4}$$
$$F'(x) = -4(2x - f(x))^{-5}\ (2x - f(x))'$$
$$F'(x) = -4(2x - f(x))^{-5}\ (2 - f'(x))$$

amistre64 · Answer

if you want it prettier i spose:

$$F'(x) =\ -4\  \frac{(2 - f'(x))}{(2x - f(x))^{5}}\ $$

amistre64 · Answer

yeah, always simplify first :) .. makes life simpler
