Answer:
x = 16
Step-by-step explanation:
To solve the equation, we need to solve for x. Since it's being square-rooted right now, we need to square it (inverse operation of square root). Since we square one side, we also need to square the other to keep the equality:
[tex](\sqrt{x})^2=4^2[/tex]
[tex]x = 16[/tex]
