Solve each equation or inequality. Round to four decimal places if necessary.
\n" ); document.write( "log base 2 of x <7
\n" ); document.write( "--------------
\n" ); document.write( "Solve the boundary equation:
\n" ); document.write( "log(base 2) x = 7
\n" ); document.write( "x = 2^7
\n" ); document.write( "x = 128\r
\n" ); document.write( "\n" ); document.write( "------------------------------
\n" ); document.write( "Plot the value x=128 on a number line.
\n" ); document.write( "Pick a test point, other than the border value; for example, x = 2.
\n" ); document.write( "Substitute into the inequality to see if you get a true statement:
\n" ); document.write( "log(base 2)2 = 7
\n" ); document.write( "2 < 2^7
\n" ); document.write( "That is true
\n" ); document.write( "All x-values on that side of the boundary but greater than zero are part of the solution set.
\n" ); document.write( "Solution is 0< x < 128 \r
