Question

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

Answer 1

`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 2

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
