The answer would be: x=8
Here’s how you solve it!
![√(2x) = 4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8esvskabyv1zg4bq4r75kyxgxs35pbh06h.png)
Square both sides to get 2x out of the square root. 4 squared is 16
2x=16
Then divide both sides by 2
X=8
Make sure to check your answer by adding the square root 2*8 =4
![√(2 * 8) = 4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/njl32mj21i6tp15pbw8fthwa1svjffayu5.png)
Then simplify and you get 4=4
Since 4=4 that means the answer is correct and you are left with your answer:
x=8
Hope this helps! :3
