WebSometimes, the radicands look different, but it's possible to simplify and get the same radicand. Example 5: Simplify. 50 + 32. Simplify both radicals: 50 + 32 = 25 ⋅ 2 + 16 ⋅ 2 = ± 5 2 ± 4 2. Now, the radicands are the same. So, we can add using the distributive property. WebThe denominator here contains a radical, but that radical is part of a larger expression. To get rid of it, I'll multiply by the conjugate in order to "simplify" this expression. The multiplication of the denominator by its conjugate results in a whole number (okay, a negative, but the point is that there aren't any radicals):
