Step 1.1

Rewrite $a^{33}$ as ${(a^{11})}^{3}$ .

$\frac{{(a^{11})}^{3} + 1}{a^{11} - a^{22} + a^{33}}$

Step 1.2

Rewrite $1$ as $1^{3}$ .

$\frac{{(a^{11})}^{3} + 1^{3}}{a^{11} - a^{22} + a^{33}}$

Step 1.3

Since both terms are perfect cubes, factor using the sum of cubes formula, $a^{3} + b^{3} = (a + b) (a^{2} - a b + b^{2})$ where $a = a^{11}$ and $b = 1$ .

$\frac{(a^{11} + 1) ({(a^{11})}^{2} - a^{11} \cdot 1 + 1^{2})}{a^{11} - a^{22} + a^{33}}$
