2^(x+1) = 9^x
\n" ); document.write( "take the log of both sides:
\n" ); document.write( "log 2^(x+1) = log 9^x
\n" ); document.write( "(x+1) log 2 = xlog 9
\n" ); document.write( "xlog 2 + log 2 = xlog 9
\n" ); document.write( "log 2 = xlog 9 - xlog 2
\n" ); document.write( "log 2 = x(log 9 - log 2)
\n" ); document.write( "log 2/(log 9 - log 2) = x
\n" ); document.write( "0.461 = x\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
