c, the left side should be log 128 or log (2^7) which comes from log 8 + log 16. log 8 = 3log2 and log 16 = 4log2, which is 3log2+4log2 = 7log2. 7log2 = log2^7 = log 128.
C is incorrect. It is the only one in which you are actually adding the numbers of the logs together - instead of multiplying (or in the case of subtraction, dividing)!
Nice short problems.
It's been 4 years since I did some log operations. Glad I can still solve them in mind. 😅

I enjoy watching your videos. Being a senior and a maths enthusiast, it's like revising my school work. Enjoying it.
If i had this guy 45 yrs ago I wouldn't have to wait for the answer!
Option C sir
Thank you,so much❤❤❤
❤❤❤
C I think
Thank you,sir❤❤❤
If I could have you as my teacher I would do high school over again.
❤❤❤❤
Sus problemas son hermosos e interesantes.
You reveal the beauty of math.
Where is my calculator? 😂
Neat!
C. Log rules don't say anything about the sum in the argument.
RAHHHHG
C
I really like your video but I would like to know when you will start teaching calculas and trigo???
All are correct except C.
He is not hungry!
NO FEEDING!
D. 2 log(2) =log(2^2)=log(4). log(4) +log(6)=log(4*6)=log(24)
Log 24= log 72-log 3. Log 24= log (72/3).
Log 24= log 6+ log 4. Log 24= log (6x4).
Log 24= 2log 2 +log 6= log(4*6).
C is only the answer
I guessed c
Log 24= log (8+16).
i havent done logs in 30 years.. i didn't get this one

A I think
B right
C, I guess
Option C
Like please
2/3 days back only I have seen your log series, hence can tell, option (C) is not correct 😊.
Regards Sir 🙏
@@ManiH810 I was taught this in class 9th ( introduction) and then in 10th..
It's been almost 30-35 years now☺️
@@88kgs oh I see.
C. is not correct. log128 = log8 + log16
C is not correct.
c
C is not correct
c is not correct just by the logic even you don't know log
C is incorrect. Adding logs equals multiplication
Thank you,so much❤❤❤
