195 = 200 - 5(1.2)^3x-2
\n" ); document.write( "-5 = -5(1.2)^3x-2
\n" ); document.write( "1 = (1.2)^3x-2
\n" ); document.write( "ln 1 = ln (1.2)^3x-2 = (3x-2)*ln(1.2)
\n" ); document.write( "0 = (3x-2)*ln(1.2)
\n" ); document.write( "Since a log (or ln) cannot equal zero, 3x - 2 must equal zero, so that
