Question

Which of the following is a radical equation?

xw3 = 13
X+ 1/3 = 13
Vx+3 = 13
x+3= V13

Answer 1

`x+3=√(13)`

Explanation:

For a radical equation, the unknown or the variable is located under the radical sign.

In this case our variable is x.

From the given options,
`√(x)+3=13` is the only radical equation.

The last equation,
`x+3=√(13)` is not a radical equation because the number (13) under the radical sign is constant.

The 3rd choice is correct
