It also can be expressed as: 

 

√45   =  √9 * √5  =   3 √5

Well if you want the EXACT answer it's 3 times the square root of 5. 
- How you get that:
1. Separate the 45 within the square root into two terms (9 times 5).

 

2. 9 is a perfect square so you can extract it out as three, leaving the five inside. Thus you get the answer above.
