It nearly killed me reading it.
YES, and although it wants to make sense, its is bouncing between my ears unclear when I try to apply. Ive been trying to short cut the process to come close to an answer.
Thanks, especially bobbym, your process I followed helps a lot.
Whew, I don't know. This is the upper limit of my ability and understanding. This is my final unit in my semester and this was a very bad unit for me. Thankfully my grades were high enough up to this point, but Im really hitting the wall on understanding the log, ln, all of that.
Solve the logorithmic equation
log(8) x + log(8) (x-63) = 2
The correct answer is listed as 64.
I'm trying to learn and understand the correct way of coming down to that answer with out using a calculator. Thanks.
Condense the logorithmic expression as much as possible:
3 ln x -(1/3) ln y
The answer is ln x^3 / 3(radical)y
Can a process be provided as to how one gets to the answer? I think I see what is happening, but could use clarification.
x = e^6 -3
THANKS
Well let me see again...
That then takes me to the next step of
x+3=e^6
Im sorry, the e concept has me very confused. I feel like Ive wasted a lot of time on these type of examples on my own.
I did it on a calculator first then tried on my own and became very confused.
Solve for x:
ln(x+3)=6
Can you explain to me how the answer is e^(6) -3
Thank you
Maybe if I re-write it.
3^(x+7)=6
That trick makes a lot of sense, but, what about when one number cannot be the same? Like the 6 below:
3^x+7=6
I'm not sure. I think I don't understand.
Sometimes I get x = -1/3 so Im not sure whats the right way to do it. :-(
I am solving for X below:
4^(3x+5) = 1/256
The answer I get is -3 please correct me if I am wrong and why if you can please. Much appreciated.
