Simplify and rationalize the denominator where necessary.
\n" ); document.write( "a) \"+sqrt%28+90+%29+%2F+++sqrt%28+3+%29+\"
\n" ); document.write( "= \"sqrt%2890%2F3%29\"
\n" ); document.write( "= \"sqrt%2830%29\"
\n" ); document.write( "-------------------
\n" ); document.write( "b) \"+15%2F++%283+%2B+sqrt%28+5+%29%29+\"
\n" ); document.write( "Multiply NUM and DEN by the conjugate of the DEN 3 - sqrt(5)
\n" ); document.write( "= \"15%283-sqrt%285%29%29%2F%289+-+5%29\"
\n" ); document.write( "= \"15%283-sqrt%285%29%29%2F4\"\r
