[tex]7 \sqrt{x}=14[/tex] is a radical equation

A radical equation is an equation that has a variable under the radical (root)

  • From the given option [tex]x+\sqrt{5}=12[/tex], you can see that a constant is a value inside a radical, not a variable. Hence this equation is not a radical equation.

  • The same is applicable to [tex]x^2=16 \ and \ 3+x \sqrt{7}=13[/tex], the variable is not under the radical function.

  • Hence the only option that is a radical equation is [tex]7 \sqrt{x}=14[/tex] since x is under the radical function.
