Express the following as a single logarithm (base is 10 unless otherwise indicated):\r
\n" ); document.write( "\n" ); document.write( "log2-log3+log5=
\n" ); document.write( "log2-(log3+log5)=
\n" ); document.write( "log2-log(3*5)=
\n" ); document.write( "log2-log15=
\n" ); document.write( "log(2/5)=0.8751\r
\n" ); document.write( "\n" ); document.write( "Now, I did this problem this way and answers don't match. Please explain why? Thank you very much. \r
\n" ); document.write( "\n" ); document.write( "(log2-log3)+log5=
\n" ); document.write( "log(2/3)+log5=
\n" ); document.write( "log((2/3)*5)=
\n" ); document.write( "log(10/3)=0.5228\r
\n" ); document.write( "\n" ); document.write( "Now, which one is the solution to the question? I am confused!!!!!!!!!! Thank you very much.
\n" ); document.write( "
The 2nd simplification is correct.
\n" ); document.write( "log 2 - log 3 + log 5 ======> \"log+%28%282%2F3%29+%2A+5%29\" ======> \"log+%28%2810%2F3%29%29\"
\n" ); document.write( "Your 1st simplification was INCORRECT and that's why you got a different answer.
\n" ); document.write( "log2 - log 3 + log 5
\n" ); document.write( "log2-(log3+log5) <========= This is INCORRECT
\n" ); document.write( "Putting parentheses around the 2nd and 3rd logs in the expression would give you: log 2 - (log 3 - log 5)
\n" ); document.write( "I hope you realize that when the OPEN PARENTHESIS is placed around log 3, the \"+\" after log 3 changes to \"-\".
\n" ); document.write( "Continuing, we get: , which is same as above. \n" ); document.write( "
\n" );
