Which of the following is a radical equation? x+√5=12

x^2=16

3+x√7=13

7√x=14

pleas i just have 20 minutes for answer the question

The answer would be: 7√x=14

A radical equation is an equation with at least one variable put on a radical form. In this question, there is only one kind of variable which is x. Then, you need to find the equation where x is in the radical form. The radical form can be expressed with square root symbol. The option with √x would be only 7√x=14
