Latex help concerning array

[chijioke]

I want to it rendered in array form and is not rendering. Why? I have searched kartex Latex, yet couldn't find help.

$\begin{array}{cc} \frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} + \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} - \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}} \\[8pt] = \left( ( - 8 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} + \left( ( - 32 ) ^ {( - \frac{ 1 }{ 5 })} \right) ^ {( - 1 )} - \left( ( - 64 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} \end{array} [\imath]$

array form … is not rendering. Why?

For the fourth time, arrays require & for columns. Please go back and re-read the responses to your previous array questions.

Even with & it is still not rendering as I intended on
$\begin{array}{cc} \frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} + \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} - \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}} \\[8pt] & = \left( ( - 8 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} + \left( ( - 32 ) ^ {( - \frac{ 1 }{ 5 })} \right) ^ {( - 1 )} - \left( ( - 64 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} \end{array} [\imath]$

It seems to be rendering what you told it to do just fine. Perhaps you should tell us what you think it should look like. What are you trying to make it do?

If you are trying to get the text to be larger, use \displaystyle
$\displaystyle \frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} + \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} - \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}}$

or [ math ] tags (instead of imath.)
$$\frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} + \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} - \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}}$$

Which array form? How many columns and how many rows? Below is an example with 3 columns and 2 rows:

$\begin{array}{ccc} \frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} &+ \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} &- \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}} \\[8pt] \\ = \left( ( - 8 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} &+ \left( ( - 32 ) ^ {( - \frac{ 1 }{ 5 })} \right) ^ {( - 1 )} &- \left( ( - 64 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} \end{array} [\imath]$

I want it to look like this

I don't see any arrays there. Are you complaining that the digits in the first line are smaller than the ones in the second line? If that's the case then you don't need arrays, but it might help to display each line separately, like this:

$$\frac{1}{(-8)^{(-\frac{1}{3})}} + \frac{1}{(-32)^{(-\frac{1}{5})}} - \frac{1}{(-64)^{(-\frac{1}{3})}}$$
$$=\left((-8)^{(-\frac{1}{3})}\right)^{(-1)} + \left((-32)^{(-\frac{1}{5})}\right)^{(-1)} - \left((-64)^{(-\frac{1}{3})}\right)^{(-1)}$$
Here is the code:

$$
\frac{1}{(-8)^{(-\frac{1}{3})}}
+
\frac{1}{(-32)^{(-\frac{1}{5})}}
-
\frac{1}{(-64)^{(-\frac{1}{3})}}
$$

$$
=\left((-8)^{(-\frac{1}{3})}\right)^{(-1)}
+
\left((-32)^{(-\frac{1}{5})}\right)^{(-1)}
-
\left((-64)^{(-\frac{1}{3})}\right)^{(-1)}
$$

$\begin{array}{cc} \frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} + \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} - \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}} \\[8pt] & = \left( ( - 8 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} + \left( ( - 32 ) ^ {( - \frac{ 1 }{ 5 })} \right) ^ {( - 1 )} - \left( ( - 64 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} \end{array} [\imath]$

Or you could do
\frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} + \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} - \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}} \\
= \left( ( - 8 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} + \left( ( - 32 ) ^ {( - \frac{ 1 }{ 5 })} \right) ^ {( - 1 )} - \left( ( - 64 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )}

$$\frac{ 1 }{( - 8 ) ^ {( - \frac{ 1 }{ 3 })}} + \frac{ 1 }{( - 32 ) ^ {( - \frac{ 1 }{ 5 })}} - \frac{ 1 }{( - 64 ) ^ {( - \frac{ 1 }{ 3 })}} \\ = \left( ( - 8 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )} + \left( ( - 32 ) ^ {( - \frac{ 1 }{ 5 })} \right) ^ {( - 1 )} - \left( ( - 64 ) ^ {( - \frac{ 1 }{ 3 })} \right) ^ {( - 1 )}$$
The \\ is used in arrays as well. It represents a break from one line to another.
