factor out 147 into 3 x 49. 49 is a perfect square
OpenStudy (anonymous):
\[\sqrt{147} = \sqrt{49*2}\] Can you do it from here?
OpenStudy (anonymous):
Crap, sorry, replace the 2 with a 3.
OpenStudy (anonymous):

OpenStudy (anonymous):
\[\sqrt{149} = 49 \times 3 = 7\sqrt{3} \] So this is simplified .
