1.find the domain of the function f(x) = ln (8x-24)
\n" ); document.write( ":
\n" ); document.write( "We can't have a negative value, (or 0) therefore: Domain: |x| x > 3
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "2. simplify log (1/10)
\n" ); document.write( ":
\n" ); document.write( "We can use the reciprocal of (1/10):
\n" ); document.write( "\"log%2810%5E-1%29\"
\n" ); document.write( "-1*log(10)
\n" ); document.write( ":
\n" ); document.write( "we know the log of 10 = 1
\n" ); document.write( "-1*1=-1
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "3. write as a single logarithm and simplify (no decimal approximations)
\n" ); document.write( ":
\n" ); document.write( "2 log 6 + log x - log 2
\n" ); document.write( "\"log%286%5E2%29+%2B+log%28x%29+-+log%282%29\"
\n" ); document.write( "\"log%2836%29+%2B+log%28x%29+-+log%282%29\"
\n" ); document.write( "\"log%28%2836x%29%2F2%29\"
\n" ); document.write( "log(18x)
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "4. expand and simplify (no approximations: ln(ex)
\n" ); document.write( ":
\n" ); document.write( "ln(e) + ln(x)
\n" ); document.write( ":
\n" ); document.write( "We know the ln of e = 1, therefore:
\n" ); document.write( "ln(x) + 1
\n" ); document.write( "
\n" );
