Thread: Radical times two other radicals(distributive property)

I need help on the procedure and rules for these kinds of problems. Here are two examples from my book.

(*=radical sign)

*2 (*2 + *3)

*3(*15 + *21)

Just imagine . This gives you: which is something you probably know how to do already.

Just keep in mind that when multiplying two radicals, you can combine the numbers under it and put it under a single radical, i.e.



Try the same thing as above.

Distribute like you would any other number, and then use this property to simplify: , where are nonnegative real numbers. Here is an example of the basic process:
