Basic Math Examples

$5^{3} + z^{3}$

Step 1

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 $a = 5$ and $b = z$ .

$(5 + z) (5^{2} - 5 z + z^{2})$

Step 2

Raise $5$ to the power of $2$ .

$(5 + z) (25 - 5 z + z^{2})$
