1. Solve the following equations
\n" ); document.write( "a) log x+1 = log 6 - log x
\n" ); document.write( "Subtracting logs means divide so we can combine on the right to
\n" ); document.write( "log(x+1) = \"log%28%286%2Fx%29%29\"
\n" ); document.write( "if the logs are equal, the values are equal, therefore:
\n" ); document.write( "x + 1 = \"6%2Fx\"
\n" ); document.write( "multiply both sides by x
\n" ); document.write( "x(x+1) = 6
\n" ); document.write( "arrange as a quadratic equation
\n" ); document.write( "x^2 + x - 6 = 0
\n" ); document.write( "Factors to
\n" ); document.write( "(x+3)(x-2)
\n" ); document.write( "Two solutions
\n" ); document.write( "x = -3
\n" ); document.write( "x = +2, this is the only solution, (we can't find the log of a neg number)
\n" ); document.write( ":
\n" ); document.write( "Check this on a calc:
\n" ); document.write( " enter: log(2+1) results: .477..
\n" ); document.write( " then
\n" ); document.write( " enter: log(6) - log(2): results: .477..; equality confirms our solution of x=2
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "b) ln(x-2) + ln(3) = ln(x+1)
\n" ); document.write( "Adding logs is multiply, combine on the left
\n" ); document.write( "ln(3(x-2)) = ln(x+1)
\n" ); document.write( "ln(3x-6) = ln(x+1)
\n" ); document.write( "therefore
\n" ); document.write( "3x - 6 = x + 1
\n" ); document.write( "3x - x = 1 + 6
\n" ); document.write( "2x = 7
\n" ); document.write( "x = 7/2
\n" ); document.write( "x = 3.5
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this on a calc replace x with 3.5:
\n" ); document.write( "enter: ln(3.5-2) + ln(3); results: 1.504..
\n" ); document.write( "enter: ln(3.5+1); results: 1.504.. confirms our solution of x=3.5
