Question

What is the solution of square root 2x+4 =16 the square root is over the 2x+4

Answer 1

Answer:

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

Step-by-step 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

Answer 2

Answer:

$x=126$

Step-by-step explanation:

$\sqrt{2x+4} =16$

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

$\sqrt{2x+4} =16$

$(\sqrt{2x+4})^2=16^2$

$2x+4= 16 \cdot 16$

$2x+4= 256$

Subtract 4 on both sides

$2x= 252$

Divide both sides by 2

$x=126$
