Am i on the right track?
radical of 3 times radical of three= radical of 9?
radical of 2x times radical of 2x= radical of 4x^2?
radical of 14 times radical of 2= radical of 28?

1st: but what is √9 ?
2nd: √(2x) √(2x) = √(4x^2) = 2x
generally: √a√a = a
3rd: √14 √2

oh ok so i have to simplify everything for it to be correct right?

except i don't understand your second point. I'm lost right there.

yes, you were not finished
for my 2nd:
The square root of a number times itself gives you the number itself
(√5)(√5) = √25 = 5
√23(√23) = √529 = 23
√a(√a) = a

oh ok i get it now i think i understand. so what if there is a little number inside the little v shape it makes

i cant make the radical sign. i don't know how

The √ symbol means square root
If you see a little 3 inside the √ , like ∛ , then it means cube root
if you see a little 4 inside the √ , like ∜ , then it means fourth root

I am making these symbols on a Mac
I don't know how to make them on my PC, that is why most of my answers on this website are done on my Mac.

ok thank you

What I have done on my PC is copy and paste useful characters I have seen in other posts. I keep them in a file for later use.
I tried inserting some cool symbols I found elsewhere on the web, and a student complained they came out as little boxes. That's due to a font incompatibility. Nowadays I stick to symbols I see in Jiskha posts.
