Answer 1

\[9 \log_{3} 4\]

Answer 2

Use the change of base formulae as shown here: http://www.purplemath.com/modules/logrules5.htm

Answer 3

\[\LARGE 9\cdot \log_34=9\cdot \log_33+9\cdot \log_31\]
\[\LARGE 9\cdot1+9\cdot 0=9\]

I'm not 100% sure, if someone could verify it .. :(

Answer 4

Kreshnik - log(a) + log(b) = log(ab) - so your solution is not correct

Answer 5

Auff... 3*1 is not 4 pfff... I see it !

Answer 6

:) - it's good to make mistakes - that's how we all learn

Answer 7

gf: you can use the change of base formulae to convert the log to base 3 into a log to base 10 and then just use a calculator to work out the result.
