By base change formula, do you mean
\n" ); document.write( " $\"y%5Ex=+a\"$ is equivalent to $\"x=+%28log+a%29%2F%28log+y%29+\"$ ???\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If so, then
\n" ); document.write( " $\"2%5Ex=5\"$ is equivalent to $\"x=+%28log+5%29%2F%28log+2%29+\"$ , which by calculator is about 2.32.\r
