\n" ); document.write( "if (125/27)^x = the cubic root of 0.6 then the value of x is . . .
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        This problem can be solved by applying brute force,  as tutor  @Theo did it.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        But it can be solved elegantly,  if to look at the numbers and to think a bit.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Notice that the ratio  \"125%2F27\"  in the left side is nothing else as  \"%285%2F3%29%5E3\".\r\n" );
document.write( "\r\n" );
document.write( "In the right side,  0.6 = \"6%2F10\" = \"3%2F5\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This suggests that the left side is  \"%285%2F3%29%5E%283x%29\",  while the right side is  \"%285%2F3%29%5E%28-1%2F3%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, our equation is\r\n" );
document.write( "\r\n" );
document.write( "    \"%285%2F3%29%5E%283x%29\" = \"%285%2F3%29%5E%28-1%2F3%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This implies\r\n" );
document.write( "\r\n" );
document.write( "    3x = \"-1%2F3\",  which gives  x = \"-1%2F9\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The solution to this equation is  x = \"-1%2F9\".\r\n" );
document.write( "
\r
\n" ); document.write( "\n" ); document.write( "Solved, and the exact solution is found.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice that \"-1%2F9\" = -0.111111111111111...\r
