Simplified radical form and rationalize all denominator
\n" ); document.write( "(3√(7))/(-1-√(27))
\n" ); document.write( "----
\n" ); document.write( "Multiply numerator and denominator by (-1+sqrt(27)) to get:
\n" ); document.write( "----
\n" ); document.write( "= [3sqrt(7)*(-1+sqrt(27))] / [(-1-sqrt(27))(-1+sqrt(27))]
\n" ); document.write( "----
\n" ); document.write( "= [-3sqrt(7)+3sqrt(7*27)]/[1-27]
\n" ); document.write( "----
\n" ); document.write( "= [-3sqrt(7)+3*3sqrt(21)]/(-26)
\n" ); document.write( "---------------
\n" ); document.write( "= [3/26][sqrt(7)-(3/26)sqrt(21)]
\n" ); document.write( "=========
