This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

log of a negative number is possible for some negative bases. However, the graph would break several times while sketching y=log x ( x<0 ) for a particular negative base. Thus we aptly say log of negative number is not possible.

A note: logarithms can be extended for negative numbers if you consider complex numbers. See here.

More accurately, logarithms can be extended to all non-zero complex numbers.
You have to be careful, as it is no longer a one-to-one function, but multivalued (which some people do not consider as a function).
