Which of the following is a radical equation? a. x sqrt 3=13 b. x+sqrt3=13 c. sqrtx+3=13 d. x+3 =sqrt 13

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:

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.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
