In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

(x - 5)² = 81

x = ?

Step 02:

(x - 5)² = 81

[tex]\begin{gathered} x\text{ - 5 = + }\sqrt[]{81} \\ x1\text{ = 9 + 5 = 14} \end{gathered}[/tex][tex]\begin{gathered} x\text{ - 5 = - }\sqrt[]{81} \\ x2\text{ = - 9 + 5 = }-\text{ 4} \end{gathered}[/tex]

x1 = 14

x2 = - 4

The answer is:

x1 = 14

x2 = -4
