How do you multiply a square root/radical with a whole number?
For example.. What's radical two times radical three?
Thank you!
If you can, please tell me how you got your answer.

sqrt(2) * 3 = 3 sqrt(2)
That is considered to be "simplest radical form".
However, if you want to take it all inside the radical, then
sqrt(2) * 3
= sqrt(2) * sqrt(9)
= sqrt(18)
On the other hand, to multiply radicals, simply do the following:
sqrt(2) * sqrt(3)
= sqrt(2*3)
= sqrt(6)
I hope this helps!

rad 2 x rad 3= rad 6 Multiply the numbers underneath the radical symbols.
square root of 4 x square root of 9 = square root of 36= 6

i saw that you posted this question before, and your problem is that your example doesnt fit your question. you said you already knew how to multiply two radicals, so radical 2 times radical 3 should be something you already know how to do.
however, if your real problem is multiplying radical 2 by 3, then your answer is 3radical(2)
hope that cleared things up =]

sqrt(6)
You just multiply the two inner numbers

If you have a^b times c^b, then the product is
(ac)^b. So your answer is sqrt(6).
