add or subtract and simplify
\n" ); document.write( "-7√147-9√108-5√243
\n" ); document.write( "= -7*sqrt(3*49) - 9*sqrt(3*36) - 5*sqrt(3^5)
\n" ); document.write( "---
\n" ); document.write( "= -7*7sqrt(3) - 9*6sqrt(3) - 5*9sqrt(3)
\n" ); document.write( "---
\n" ); document.write( "= (-49 - 54 - 45)sqrt(3)
\n" ); document.write( "---
\n" ); document.write( "= -148sqrt(3)
\n" ); document.write( "============================
\n" ); document.write( "133√3 + 33√3 = 166sqrt(3)
\n" ); document.write( "============================
\n" ); document.write( "23√a + 3√27a
\n" ); document.write( "23sqrt(a) + 3*3sqrt(3a)
