document.write( "b) \"log0.135\"       <<<--- To solve it, apply your calculator or computer . . .  Or apply special tables for logarithms, if you have it. \r\n" );
document.write( "                               It is the only way in this case.  // The other way is to expand it in series, but nobody will do it in our days.\r\n" );
document.write( "                               When you ask other people to do it for you, you simply shift/move your work to their shoulders. \r\n" );

document.write( "\r\n" );
document.write( "c) \"log%287%2C22%29\"      <<<--- Apply the formula for the base change for logarithms,  \"log%28a%2Cx%29+=+log%28b%2Cx%29%2Flog%28b%2Ca%29\",  and you will get \"log%287%2C22%29\" = \"log%28%2822%29%29%2Flog%28%287%29%29\" with decimal logarithms.\r\n" );
