I have the answer can someone just check to see if I'm right. WHich of the following is f '(x) for f(x)=(ln3)x^2+(ln2)e^x

OpenStudy (anonymous):

What was your answer?

OpenStudy (anonymous):

I got (ln6)x+(ln2)e^x

OpenStudy (anonymous):

no that is not right

OpenStudy (anonymous):

i think u mean ln(9)

OpenStudy (anonymous):

just try differentiating the x since ln of 6 is just a constant

OpenStudy (anonymous):

2ln(3) -> ln(3^2)

OpenStudy (anonymous):

so everything is correct apart from ln(6) should be ln(9)

OpenStudy (anonymous):

so mean like 2(ln3x)+2x

OpenStudy (anonymous):

no

OpenStudy (anonymous):

this is what u wrote (ln6)x+(ln2)e^x

OpenStudy (anonymous):

change the 6 to 9

OpenStudy (anonymous):

you mean and then I would have my answer?

OpenStudy (anonymous):

yes well done

OpenStudy (anonymous):

but all of my multiple choice answers don't have a 9 in them

OpenStudy (anonymous):

ok then 2ln(3)

OpenStudy (anonymous):

its the same as ln(9)

OpenStudy (anonymous):

ok but then should the x be in the parenthasis or outside

OpenStudy (anonymous):

outside 2xln(3)

OpenStudy (anonymous):

or x2ln(3)

OpenStudy (anonymous):

or 2(ln3)x+(ln2)e^x

OpenStudy (anonymous):

exactly

OpenStudy (anonymous):

they are all the same

OpenStudy (anonymous):

ok thanks

OpenStudy (anonymous):

did u get yesterday's question right or not?

OpenStudy (anonymous):

yeah I did

OpenStudy (anonymous):

do u want me to solve it for u in details

OpenStudy (anonymous):

good
