{ \green{ \sf{ √(x + 8) = 8}}}

square on both the sides


{ \green{ \sf{ {({{√(x + 8))}}^(2)} = {(8)}^(2)}}}


{ \green{ \sf{x + 8 = 64}}}

Add -8 on both the sides


{ \green{ \sf{ x { \cancel{+ 8}} { \cancel{-8}} = { 64 - 8}}}}


{ \green{ \sf{x = 64 - 8}}}


{ \green{ \boxed{ \red{ \sf{x = 56}}}}}

Explanation:

(square both sides to get rid of the square root.

x+8=(8)^2

x+8=64

x=56
