Answer:


x=126

Explanation:


√(2x+4) =16

To find solution , we need to solve for x

In order to get x alone, eliminate the square root

To remove square root , take square on both sides


√(2x+4) =16


(√(2x+4))^2=16^2


2x+4= 16 \cdot 16


2x+4= 256

Subtract 4 on both sides


2x= 252

Divide both sides by 2


x=126

Answer:

The solution of square root 2x+4 =16 is x = 126

Explanation:

It is given that

square root (2x+4 )=16

√(2x+4 )=16 ----- (1)

Squaring both side of equation we get

[√(2x+4 )]^2=16^2

2x + 4 = 256

2x = 256 - 4

2x = 252

x = 252/2 = 126

Therefore the solution of square root 2x+4 =16 is x = 126
