a. ln Ce^-at
ln a^b=b ln a
ln Ce^-at = -at ln Ce
ln(a * b) =ln a + ln b
ln Ce^-at = -at ln Ce = -at(lnC + ln e)
ln e=1
ln Ce^-at = -at ln Ce = -at(lnC + ln e)=-at(lnC+1)
Hi!
I am taking AP Calc AB and my new teacher sent us a math assignment to do over the summer.
There is this question that stumped me.
Evaluate or simplify
a. ln Ce^-at
I have never seen something like this in my life! I tried googling it but no answer. Obviously it has something to do with logarithms and natural logs because of the "ln". How would I simplify/evaluate?
Just to check my work for letter b the problem is:
log4 (1/8)
that would be 4^x= 1/8 right?
Thanks!
