we are supposed to multiply the square roots and write the answer in simplified radical form.

Yes.  Break down the radicals by their factors.  At least on factor should be a perfect square.
 
 
√(1.5) * √(150) =
 
√(3/2) * √(25)√(6)
 
 
Can you finish the rest?
 
Be sure to rationalize any denominator if the denominator has a radical in it.

Michael,
I'm fairly sure that 
150 ≠ (100)(25)(5)

I seemed to have made a typo that I did not see.  But, I should not get a downvote just for a minor typo.  Whoever gave me the downvote is paying too much attention to minor typos rather than errors in procedure.

Uhm... Michael,
150 also does not equal 100(15)....

√1.5 * √150 = √(3/2) * √(100*1.5)
 
= √(3/2) * √(100(3/2))
 
= √(3/2)*√(3/2)*√100
 
= 3/2 * 10
 
= 3*5
 
= 15

Michael, you can go in and edit your answer so others who come along aren't confused.  Just a suggestion.

I usually edit my answers, but I did not spot any errors, until another tutor made it known.  Then I realized what I did.

Michael,
Hope you realize I wasn't trying to be a pain.  Just want to avoid confusion with the students.  I've certainly made my share of typos in here.  If I could go back after edits and delete comments, I would. Keep on trucking my friend.  :-)
