In this video, we are going to divide radical expressions.
One simple example is:
By simplifying the numerator and the denominator, we now have
A slightly more difficult problem would be:
Just like the other problem, first find perfect square factors for each expression
Simplify each expression
And the final answer is
If the expression has a radical in the denominator and a rational number in the numerator, then it is necessary to rationalize the fraction.
Multiple the denominator to both the numerator and the denominator. Like terms cancel each other out so the final answer is:
