\"+log%28+81%2C+3+%29+\"
\n" ); document.write( "This is asking:
\n" ); document.write( "\" What is the exponent that I raise the base \"+81+\" to
\n" ); document.write( "that will give me the answer \"+3+\"
\n" ); document.write( "I can restate this as:
\n" ); document.write( "\"+81%5Ex+=+3+\", where
\n" ); document.write( "\"+x+=+log%28+81%2C3+%29+\"
\n" ); document.write( "----------------------
\n" ); document.write( "\"+x+=+1%2F4+\" because
\n" ); document.write( "\"+root%28+4%2C+81+%29+=+3+\"
\n" ); document.write( "Raise both sides to the 4th power
\n" ); document.write( "\"+%28+root%28+4%2C81+%29+%29%5E4+=+3%5E4+\"
\n" ); document.write( "\"+81+=+81+\"
\n" ); document.write( "Hope this helps
