Hope this helps.
I'm not sure if you wrote log2(2x-5) or log2(2x) - 5 though...
But I assume it's log2(2x-5)

Thank you for solve this problem and explain it to me
U really help me a lot.i hope you can help me when I got any questions
No problem. Glad I was able to help.
I would like to ask something.why i need to change the base to base 2
This is to make the right hand side into a number, which is easier to work with.
You can also write log8(2) = log8(8^(1/3))
= (1/3)log8(8) = 1/3
= (1/3)log8(8) = 1/3
Am I need to follow the base of the log inside the bracket in the left side
What do you mean?
I mean do I need to follow the base 2 in the log 27(log base 2 ^2x-5)in the left side when I change the base in the right side
Can you show me that step more detailly
No, you don't have to follow. But for this question, it just happens that the base for the right hand side also changes to 2.
Oh
Clement Cheng I have another similar question.can I send it to you
Sure
Log16(log3^2x-1)=log4^2
The 2nd and 3rd log terms don't have bases?
Can I clarify if it's log(base 3)(2x - 1) or log(base3)(2x) -1 ?
Got.the second log base is 3 and third log is 4.sorry .I forget to write base there.
The first statement
Log(base 3)(2x-1)=log (base4)(2)
Ok thanks

Why need to change the base to base 2 in the left side
I didn't change the base on the left side. The right side change to base 2, so I can remove the log in the end.
You can also do for the right hand side:
log(base4)2 = log(base4)4^(1/2)
= (1/2)log(base4)4 = 1/2
You can also do for the right hand side:
log(base4)2 = log(base4)4^(1/2)
= (1/2)log(base4)4 = 1/2
Can I change the log base to base 2 by seeing the power on the base in the right side to remove the log.for example , I use this question.can I change the base to 2 by seeing the power 2 on the top of the base 4 in the right side
Why does the base have a power?
The base is changed to 2 so that it becomes (log(base2)2) / (log(base2)4) which is 1/2
Is the picture that I sent is correct
The answer
correct
Thank you Clement Cheng for explaining it patiently to me
I will send you message you if I got any other questions.can i
The numbers after the base is not it's power. They should be just normal numbers.
i.e. log(base4)2 and not log(base4)^2
i.e. log(base4)2 and not log(base4)^2
No problem glad to help
Oh.i understand now.thank you
Clement, are you free now? I got another question
U also can send me the answer tomorrow
You can send me now.
I already posted it in asking section
Em can I ask if it's 9^(log(base3)x) or
9 * (log(base3)x) ?
9 * (log(base3)x) ?
I think it is the second statement
9*(log(base3)x)=4
I would like to ask how to do the second statement
Can you show me how to do the second statement
U can also send me tomorrow
Goodnight
Ok. Goodnight.
Ok
Clement can you help me to solve my question
