\"log%285%2C%281%2F25%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Remember the definition: \"y=log%28b%2C%28x%29%29\" if and only if \"b%5Ey=x\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So: \"y=log%285%2C%281%2F25%29%29\" if and only if \"5%5Ey=1%2F25\". Since \"25=5%5E2\", \"1%2F25=5%5E-2\", so \"y=-2\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence: \"log%285%2C%281%2F25%29%29=-2\"
\n" ); document.write( " \n" ); document.write( "
