What does log2 represent without a base? How is calculation done with such two expressions?
How do we formulate two expressions of log with same base but different coefficients? Like 2log 10(base) 25/7 + log 10(base) 16.
Please say because its urgent. Proper answer will be marked brainliest.

without base the base means ' e ' it is an irrational number which is thought to be between 2 and 3.
2log 10 25/7 = log 10 625/49
log 10 625/49 + log 10 16 = log 10 (625*16)/49

ankurivup9fgqm: ok ishana, i have a good solution for your problem with logarithm. just search on youtube about it and you'll get amazing worthy videos.
ankurivup9fgqm: bytheWay, i also read in WB board. but i cant say my class
ishanaghosh: Why not
ishanaghosh: Well I guess you read in class 12, isn't it so?
ankurivup9fgqm: nope
ankurivup9fgqm: class 11
ankurivup9fgqm: i just gave madhyamik exam this year
ishanaghosh: Sorry. I just calculated your age and...
ankurivup9fgqm: oh
ankurivup9fgqm: all the best for your madhyamik

when there's no base, that can mean two things.
1. the base is 10 (for algebra)
2. the base is e (for calculus)
well e is a constant just like π

now the next question's answer is in the picture.

ishanaghosh: Thanks a lot.
ishanaghosh: Well, hour way of answering is absolutely better but as I had said swarna rup that I will mark him brainliest if he answers all my questions in comments, i had to mark him.
ishanaghosh: Thank you.
ishanaghosh: Well, as we have not learned calculus, then the nase is 10. Right?
ishanaghosh: Base and not nase
ankurivup9fgqm: yup. and there's another thing. when the base is e. suppose log e (base) something. we can also say it as ln something
Swarnarup: of course u can get the ln term in calculators
ankurivup9fgqm: yeah
