Definition:Bimedial/Second Bimedial

Definition
Let $a, b \in \R_{>0}$ be in the forms:
 * $a = k^{1/4} \rho$
 * $b = \dfrac {\lambda^{1/2} \rho} {k^{1/4} }$

where:
 * $\rho$ is a rational number
 * $k$ is a rational number whose square root is irrational.
 * $\lambda$ is a rational number whose square root is irrational.

Then $a + b$ is a second bimedial.
