I found my c to be 3.366 but the answer is wrong

yes, i know how to do it..but got it wrong.. don't know why

Does it want an approximation?

it didn't say..so i'm thinking should the answer be an exact number

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
but then i think there is only 1 number c

Well the number you put above is not the exact answer

myininaya Group TitleBest ResponseYou've already chosen the best response.2
That is call an appoximation

how do get an exact number?

myininaya Group TitleBest ResponseYou've already chosen the best response.2
So I assume you did the setup right because you got the approximation to the correct answer

myininaya Group TitleBest ResponseYou've already chosen the best response.2
This is the setup you chose? \[\frac{1}{c}=\frac{\ln(8)\ln(1)}{81}\]

myininaya Group TitleBest ResponseYou've already chosen the best response.2
We know ln(1) =? and 81=? So can you tell me what 1/c= Don't use your calculator

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
and then f'(c) = 1/c then solve for c
 2 years ago

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
ln 1 = 0 81= 7
 2 years ago

myininaya Group TitleBest ResponseYou've already chosen the best response.2
Ok we have \[\frac{1}{c}=\frac{\ln(8)0}{7}\] Do you know how to solve this for c?
 2 years ago

lovekblue Group TitleBest ResponseYou've already chosen the best response.0
ln 8/ 7 = 1/c c= 7/ln8
