This week in Pre Calc 11 we learned how to divide and multiply radicals. In this blog post, I’ll be focusing on the division of radicals.

With a problem like this there is a simple solution, because each radical is divisible by 6.

it becomes

simplify to

The answer is

However, with a problem such as   it becomes slightly more complicated. Although it’s still pretty straightforward, as we already know everything we need to about division to solve this.

Multiple both the denominator and the numerator by the denominator to rationalize it.  x x x
