Hi Nandhini,

Logarithms are not difficult and when you understand them, they are very interesting too. For example, if you wanted to plot a graph with the following three numbers (1) 100, (2) 1000000, and (3) 20000000000 on the same Y-axis it would be pretty much impossible to do it with a linear graph but with a logarithmic graph it would be simple.

A great place to learn logarithms is on Khan Academy. See the link below.

Good luck!

Andrew’s Answer

It is not difficult at all, it is more like learning a new concept. Since you are comfortable with the basic, you feel it is hard to learn a new concept. take time and keep study, it will sink in. make it into real language and you will make it very clear.

Example: 5^x = 100 is hard to understand but if you say "How many 5 to multiply with each other to get 100?"
the answer is about 2.86135.

Saurabh’s Answer

Logarithm is not difficult. The thing is you have to understand the basics well and spend some time solving problems. I also used to think like you when I was in high school but instead of cornering it away due to fears , I fought with it and eventually conquered it. See it is human nature, if you encounter anything which you don't know then it seems to be hard. See doing surgery for a surgeon is easier for him as compared to you because you have never done that. Once you become surgeon, it becomes easy for you as well.

What I would suggest is get a good book, practice basics and then practice from a standard book. If you do this, I believe logarithm would become a cake walk for you.

Saurabh recommends the following next steps:

watch Youtube videos for basic logarithms. You can Filter videos by number of views/likes to save time.
make notes of basics for future reference
Get a standard book and practice some 150-200 questions over span of one or two weeks (daily 15-20 questions or as per your convenience)
