Is radical 3 a real number?
No it is not.
Can you divide a radical by a real whole number?
Yes.
Any radical expression with a radicand and an even index is not a real number?
negative
Any radical expression with a negative radicand and a index is a real number?
Odd
When you multiply a radical number with another radical number do the radical signs cancel each other out?
Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30

I'm not quite sure, but when the number inside the radical (square root sign) is negative, there is a no real-number solution.
What is the number under the radical?
A number under a radical sign is known as a radicand.
What is the number under the radical sign known as?
The number under the radical sign (also known as the radical) is called the radican.
Is radical six a real number?
Sure. √6 , the square root of 6, is approximately 2.44949. It's an irrational number --you can't get it as the ratio of any two integers -- but it's real. See Can_a_real_number_be_an_irrational_number
