Proceed and solve for x in terms of ln.
I get x=ln(8)/ln(25).
How do I proceed? I really have no clue where to go from where I've stopped! Usually I can simply factor out an x from the LS, but here I can't do that. Could you please show me your solution with every step? It would be so helpful.
Thank you in advance :)
It is a linear equation with numerical coefficients (log4, etc.).
xlog4 + 4xlog5 - 2x = 3 -3log5
Factor out x on the LHS and solve for x.
All the log4, log5 are numerical values that you can simplify eventually.
Sorry to keep bugging, but I followed what you told me and got to:
How can I get to the answer from that? I don't know how to deal with the 3 and the -2 that are still lying around.
Alright, what I did now was:
since log10=1, log100=2, and log1000=3
So I plugged that in to what I had
Is that what I was supposed to do?
