Hi;

What does the book say is the right answer for 16i?

I am trying to move to the next town over. It is only 2 miles away. Unfortunately, I might be having to go very close to NY. I hate the weather there but I may not have a choice.

Your 15th answer is again wrong. Do you want the answer of question 15?

Hmm I know the weather is colder there but don't worry you will soon get adjusted there.

Yeah I know, (and I was the first few of them to know about it) so I was not expecting a reply. I wanted other members to give answers but till now I haven't received a single one.

The answer to # 15 is log(12).

Yes it's correct.

Please recommend some outstanding incredibly difficult mathematical exercise books to me. We don't all have the same talents, but we all have the same opportunities to develop them. A man becomes flawless by practise.

There is no alternative for dedication.
