I get it.
I see! You can proceed now.
What is the meaning of e?
Find X;
Log(3x - 1) - log2 = 3
That is it.
Errr, ok, I see. I have another, but maybe tommorow or today would post it.
How about if the 3x had been x^2? Could one use log?
Ok, I get you, thank you!
Please if you wouldn't mind use log to solve it completely, and let me see how you would have solve it by using log, please!
In fact I factorised it and had 1 or 2 as answers. But since you suggested that log should be used so I agreed. Actually, wanted to learn more of log that is why I did not tell you that I have factorised
Ok,
x^2 + 2 = 3x
x^2 - 3x + 2 = taking log
Log(x^2/3x) + log2 = o
This is how I would solve it.
No don't. What I have said so far is what the book used to solve similar ones. Please, then help me
Then taking antilog, will tha help?
Then multiplying 3x through.
I want to move log2 to the right handside
Yes, I do.
In fact, I am stuck, please help.
Then see;
logx^2 - log3x + log2 =
log( x^2/3x) = -log2 > law of logarithm.
logx^2 = -log2*log3
Is this steps correct?
Hi;
2logx - log3x + log2 = 0
x(2log10 - log3) = -log2
x = -log2/(2log10 - log3)
Is this correct?
Thank you
But the link could not open for me when I try it says "the search returned no hits" I don't understand why that.
But I would like to put this across, in fact the x^2 has me thinking about it,
Find the truth set of the equation;
3^(x^2 + 2) = 27^x
Thanks Bobbym,
I wish I learn it! Because in case of any cubic equation I can't do it
Have you learned how to graph functions?
No
(Sorry I was interrupted)
Please sorry if I am bothering you much - if yok wouldn't mind I will like to learn your steps once and for all.
Thank you very much
I must learn how to factor cubics
I am stuck I can't do it
