Evaluate the limit of each indeterminate quotient:

\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The numerator has the square roots, so we \r\n" );
document.write( "multiply top and bottom by the conjugate of the\r\n" );
document.write( "numerator, which is \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "If you \"FOIL\" out the top the middle two terms\r\n" );
document.write( "cancel and we get:\r\n" );
