\"4=32%5E%281-2x%29+\"
\n" ); document.write( "take log base 32 of both sides to get:
\n" ); document.write( "\"log%2832%2C4%29+=+log%2832%2C32%5E%281-2x%29%29+\"
\n" ); document.write( "on the right, it just reduces to:
\n" ); document.write( "\"log%2832%2C4%29+=+%281-2x%29+\"
\n" ); document.write( "apply \"change of base\" to the left:
\n" ); document.write( "\"log%284%29%2Flog%2832%29+=+1-2x+\"
\n" ); document.write( "\"log%284%29%2Flog%2832%29+-+1+=+-2x+\"
\n" ); document.write( "multiplying both sides by -1:
\n" ); document.write( "\"+-log%284%29%2Flog%2832%29+%2B+1+=+2x+\"
\n" ); document.write( "or
\n" ); document.write( "\"+1-log%284%29%2Flog%2832%29+=+2x+\"
\n" ); document.write( "dividing both sides by 2:
\n" ); document.write( "\"+%281-log%284%29%2Flog%2832%29%29%2F2+=+x+\"
\n" ); document.write( "\"+%281-0.4%29%2F2+=+x+\"
\n" ); document.write( "\"+%280.6%29%2F2+=+x+\"
\n" ); document.write( "\"+0.3+=+x+\"
\n" ); document.write( "to four significant places:
\n" ); document.write( "\"+0.3000+=+x+\"
\n" ); document.write( "
\n" ); document.write( "
