Do you want the decimal or a simplified form of the logarithm?
In decimal. Thanks.
Well, your problem is probably due to the confusion between log base e and base 10. Base e is symbolized as "ln" on your calculator, while base 10 is symbolised as "log" for the question, do you mean or ? And in what base are those logs?
The first one.... 2(lg4)^2 That is exactly the question shown.

For log base 10, = 0.724952... For log base e = 3.843624...
I've scanned the questions from the textbook. Questions a) and b), I have no problem. But questions c), d) and f) are problems. Thanks GUSBOB. But the answers are still incorrect. Wondering the text book has wrong answers.
