This lesson will help you learn the basic properties and rules that govern math problem-solving.
In algebra, a fraction could contain a radical. Whether the radical is in the numerator or the denominator, make sure it is simplified.
When a radical is in the denominator, we usually use multiplication to remove the radical. We will use the idea that for any number, the square of a square root equals the number itself: $$\sqrt a \,\cdot \,\sqrt a \, = a$$.
