4 minus radical 3 over 7... rationalize the numerator
\n" ); document.write( "-------------------
\n" ); document.write( "(4-sqrt(3))/7
\n" ); document.write( "----
\n" ); document.write( "Multiply numerator and denominator by (4+sqrt(3))
\n" ); document.write( "----
\n" ); document.write( "= [(4-sqrt(3))(4+sqrt(3))]/[7(4+sqrt(3))]
\n" ); document.write( "---
\n" ); document.write( "= [16-3]/[28+7sqrt(3)]
\n" ); document.write( "---
\n" ); document.write( "= 13/[28+7sqrt(3)]
