Step 2.1

Subtract $8$ from both sides of the equation.

$a^{3} = 26 - 8$

Step 2.2

Subtract $8$ from $26$ .

$a^{3} = 18$

Step 3

Take the specified root of both sides of the equation to eliminate the exponent on the left side.

$a = \sqrt[3]{18}$

Step 4

The result can be shown in multiple forms.
