The answer for this question is C. 
First subtract the 3 from both sides to get : sqrt(x) = 10
Then square both sides to get: x = 100
The other equations can't simply proving that they cannot be radical equations
Hope this helps :)

We want to see which of the given equations is a radical equation, the correct option is C: √(x + 3) = 13.

So we define a radical equation as an equation where the variable, x, is in the argument of a root. Something like:

√x = A

Now, the given options are:

  • a. x*√3 = 13
  • b. x + √3 = 13
  • c. √(x+3) = 13
  • d. x+3 = √13

Notice that the only option where the variable is in the argument of the square root is in option C, thus the correct option is C.
