You can put this solution on YOUR website!
I found this on the net:
\n" ); document.write( "--------------------------
\n" ); document.write( "\" In general, if you want to insert X geometric means between A and B, divide A and B (B/A).
\n" ); document.write( "Then find its (X + 1) th root of B/A. That is the common
\n" ); document.write( "ratio, then multiply the common ratio by A or
\n" ); document.write( "until you have finished inserting all geometric means. \"
\n" ); document.write( "Following this:
\n" ); document.write( "\"+B%2FA+=+648%2F8+\"
\n" ); document.write( "\"+B%2FA+=+81+\"
\n" ); document.write( "The \"+X+%2B+1+\"th root would be the 4th root, so
\n" ); document.write( "\"+root%28+4%2C81+%29+=+3+\"
\n" ); document.write( "\"+8%2A3+=+24+\"
\n" ); document.write( "\"+3%2A24+=+72+\"
\n" ); document.write( "\"+3%2A72+=+216+\"
\n" ); document.write( "-----------------
\n" ); document.write( "the 3 geometric means are: 24, 72 and 216
\n" ); document.write( "-----------------
\n" ); document.write( "check answer:
\n" ); document.write( "Is \"+3%2A216+=+648+\" ?
\n" ); document.write( "yes
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
