Answer:

solution of the given expression is ( 5 ±√81 ).

Step-by-step explanation:  

( x - 5 )² = 81 is the expression and we have to get the solutions.

( x - 5 )² = 81

x - 5 = ±√81 ( if x² = 9 then x = ± 1 is the solution )

x = 5 ± √81

Therefore, solution of the given expression is ( 5 ±√81 ).
