Dividing Radical Expressions. A common way of dividing the radical expression is to have the denominator that contain no radicals. We have, $$\Large \frac{2}{{\sqrt 3 }} = \Large \frac{2}{{\sqrt 3 }} \cdot \Large \frac{{\sqrt 3 }}{{\sqrt 3 }}$$. Note that a radical still remains in the expression. If we apply the quotient rule for radicals and write it as a single cube root, we will be able to reduce the fractional radicand. Subjects: Math, Algebra, Algebra 2. The converse of this definition is also true. For all real values, a and b, b ≠ 0 . Definition: If $$a\sqrt b + c\sqrt d$$ is a radical expression, then the conjugate is $$a\sqrt b - c\sqrt d$$.
