# Now that I know how to solve radical equations, I can use models that are radical functions to determine the value of independent variable when a function value is known. We need to determine whether this statement makes sense or not.

Yes, the statement makes sense. If we know the value of a radical function, we can determine the value of the independent variable using the function value.
Example,
$\sqrt{\left(\sqrt{x}\right)}=2$
taking ${4}^{\frac{1}{2}}$ power on both sides, we have
$\left(\sqrt{\left(\sqrt{x}\right)}{\right)}^{4}={2}^{4}$
$\left(x\right)=16$
Since we knew the value of the radical function, we could calculate the value of the independent variable.
