does anyone know how to simplify using radicals?

square root 121/144 How do I simplify using radicals???

First, you apply the property of radicals that says:

\(\displaystyle \sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}\)

Do you understand this property? It tells us that we can change the square root of a fraction into a fraction of square roots, and vice versa.

Second, you recognize (because you've already memorized the multiplication table through 12 times 12, yes?) that:

(11)(11) = 121 and (12)(12) = 144

Of course, if you have not yet learned the meaning of the symbol \(\displaystyle \sqrt{}\), then you're not ready for this exercise. Do you understand what a square root is?

I'm not sure why you're stuck in this exercise because your request for help is a little vague. Are you able to ask direct questions about the specific parts of this exercise that you do not understand? This, along with any work that you've already done, is the best way for us to understand where to begin helping you.

If you think that another example (similar to those in your lessons) will help, let me know, and I will create an example for you, but if you do not understand what the symbol \(\displaystyle \sqrt{}\) represents, then you'd better say so right away.
