(3sqrt5)(2sqrt10)

I got:6sqrt50
Is this correct.?

You can take this one step further.

6√50 can be simplified to this:

6√(25 * 2) -->you can take the square root of 25.

6 * 5 √2 = 30√2 -->this is the simplified form.

thanks can you help me with my other one.?

Of course! I'd be happy to help with your other question. Just let me know what it is.
