[tex]3d = \sqrt{d+5}[/tex] is a radical equation.
What is a radical equation?
A radical equation is an equation in which a variable is under a radical.
According to the given question.
We have some equation in variables d, n, and h.
If we see the given equation only the equation [tex]3d = \sqrt{d+5}[/tex] is a radical equation because this is a equation in variable d and its variable is under radical sign(√).
And the other equations are not radical equations because no single variable of the given equations is under radical sign(√).
Hence, [tex]3d = \sqrt{d+5}[/tex] is a radical equation.
