document.write( "\r\n" );
document.write( "y = 2*10^(t/12) = 2 * (10^(1/12))^t.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "I hope you do understand this identity and do unferstand why it is valid.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next step  10^(1/12) = 1.2115 = 1 + 0.2115.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore  y = 2*(1+0.2115)^t  is that form you are looking for.\r\n" );
