Can you, and how do you simplify this further?
\(d=\sqrt{x^2+\frac{b^2}{a^2}}\)
\(d=\sqrt{x^2+\frac{b^2}{a^2}} \\ d=\sqrt{x^2+\left(\frac{b}{a} \right)^2 } \\\)
d = sqrt ( x^2 + b^2 / a^2) =
sqrt ( [a^2x^2 + b^2] / a^2 ) =
sqrt ( [ax]^2 + b^2 ) / a [whether this is any "simpler," or not, could be debated !!!! ]
