√(x+8)=8

Question

`√(x+8)=8`

Answer 1

`{ \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}}}}}`

Answer 2

Answer76

Explanation:

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

x+8=(8)^2

x+8=64

x=56
