Week 4 in Precalc 11 – Dividing Radicals

This week in Precalc 11 I learned how to divide radicals, it is important to know especially when you are simplifying or solving equations with radicals.

Here’s how you do it! In others for us to divide radicals first we must check if the radicals share the same index. In our example 2 (square) is our index. Then divide the radicand by the radicand and the coefficient by the coefficient.

Example:


Some of you might be confused where the ones come from but remembers, there are always invisible 1s (coefficient) in-front of your radical. This is just and example to remind you.

There are also in some situations where your if the denominator will contain an irrational number under the radical. What you then do is simply multiply the both the numerator and the denominator by the denominator. This will then convert it from irrational to rational.


Thank you again for coming back to another blog post and see ya again next week!
