Question 1037598
Simplify: 
sqrt45sqrt2000 
I can solve up to: 
sqrt45 => sqrt9*5 => 3sqrt5 
When I get up to sqrt2000, 
I'm having trouble in deciding what numbers to use to break it down. 
-----
2000 = 100*20 = 100*4*5
----
sqrt(2000) = sqrt(100*4*5) = 10*2*sqrt(5) = 20*sqrt(5)
------------
Cheers,
Stan H.
