Simplify square roots by finding perfect square factors. 9 is a perfect square and it is a factor of 630. So
\n" ); document.write( " $\"sqrt%28630%29+=+sqrt%289%2A70%29\"$
\n" ); document.write( "There are no other perfect square factors. Now we can use a property of radicals, $\"sqrt%28a%2Ab%29+=+sqrt%28a%29%2Asqrt%28b%29\"$ , to split this square root:
\n" ); document.write( " $\"sqrt%28630%29+=+sqrt%289%2A70%29+=+sqrt%289%29%2Asqrt%2870%29\"$
\n" ); document.write( "The square root of 9 is 3 so we can replace it with a 3:
\n" ); document.write( " $\"sqrt%28630%29+=+sqrt%289%2A70%29+=+sqrt%289%29%2Asqrt%2870%29+=+3%2Asqrt%2870%29\"$
\n" ); document.write( "This is as far as this square root can be simplified.

\n" ); document.write( "BTW, 625 is 25 squared. Or 25 is the square root of 625. Not \"perfect square of 625 is 25\"
\n" ); document.write( " \n" ); document.write( "
