$\"+6%2Asqrt%28+2+%29%2F+sqrt%28+21+%29\"$
\n" ); document.write( "multiply by square root of 21 over itself to get rid of the radical in the denominator
\n" ); document.write( " $\"+6%2Asqrt%28+2+%29%2F+sqrt%28+21+%29\"$ * $\"+sqrt%28+21+%29%2F+sqrt%28+21+%29\"$ = $\"+6%2Asqrt%282%2A21+%29%2F+21\"$ = $\"+6%2Asqrt%2842%29%2F+21\"$
\n" ); document.write( "Reduce the fraction to
\n" ); document.write( " $\"+2%2Asqrt%2842+%29%2F7\"$
\n" ); document.write( "we can rewrite this, put the denominator inside the radical
\n" ); document.write( " $\"+2%2Asqrt%2842%2F49%29\"$
\n" ); document.write( "reduce the fraction inside the radical to
\n" ); document.write( " $\"+2%2Asqrt%286%2F7%29\"$ \n" ); document.write( "
