I have a log question which asks me to express the log of a single number?

The examples I have seen are in both decimal answers and fractions, I am wondering what way the answer to a log question should be given?

It depends on the question, really. Generally, I'd go with fractions because they tend to be easier to look at/work with, particularly with logs, and they give you an exact result whereas decimals can't always do that.

I have worked out the answer which is 3.10 or log9 30 / log9 3, the questions says the result should be a number, so I assume that 3.10 is the answer, but am not sure whether I should answer it as 3 or 3.10?

This is ideal, however the OP should check with their teacher. I remember in one of my previous modules, anything with logs in the final answer was not deemed "fully simplified" - the mark scheme would specify that either a decimal or a fractional equivalent were acceptable. And I won't even

I believe the methods shown have given me a more in depth understanding of the log system although I had already previously worked out the solution myself, the members of this forum that have given clarification for me

**I would like to say thank you for your support**.

I have contacted my tutor for clarification with regards how to present the answer, so will have to wait until I get a response, which I know will be soon, so I will advise of what I am told later.
