\n" ); document.write( "1. x = 2^x+1 = 27
\n" ); document.write( "2. x = 4x+2 = 256
\n" ); document.write( "3. x = 42x+2 = 256\r

You can put this solution on YOUR website!

\n" ); document.write( "1.
\n" ); document.write( "2^x + 1 = 27
\n" ); document.write( "2^x = 27 - 1
\n" ); document.write( "2^x = 26
\n" ); document.write( "using nat logs
\n" ); document.write( "ln(2^x) = ln(26)
\n" ); document.write( "use the log equiv of exponents
\n" ); document.write( "x*ln(2) = ln(26)
\n" ); document.write( ".693x = 3.358
