Solve for t
\n" ); document.write( "10^(7t) = 18^(2t-5)
\n" ); document.write( "7tlog10=(2t-5)log18
\n" ); document.write( "7t/2t-5=log18/log10≈1.2553
\n" ); document.write( "7t=1.2553(2t-5)=2.5105t-6.2764
\n" ); document.write( "7t-2.5105t=-6.2764
\n" ); document.write( "4.4894t=-6.2764
\n" ); document.write( "t≈-6.2764/4.4894
\n" ); document.write( "t≈-1.3980
\n" ); document.write( " \n" ); document.write( "

\n" );
