Question

expand the following function
ln(a(b-4)^2 e^(4c^2))

Answer 1

\[\ln(a(b-4)^2e^{4c^2})\]
it this right:

Answer 2

yes

Answer 3

have you tried using the product rule yet?
\[\ln(a \cdot b)=\ln(a)+\ln(b)\]

Answer 4

this is what i got but im not sure lna+2ln(b-4)+4c^2

Answer 5

this is what i got but im not sure lna+2ln(b-4)+4c^2

Answer 6

\[\ln(a)+\ln((b-4)^2)+\ln(e^{4c^2} ) \text{ by product rule } \\ \ln(a)+2 \ln(b-4)+\ln(e^{4c^2}) \text{ by power rule } \\ \ln(a)+2 \ln(b-4)+4c^2 \text{ using the inverse fact}\]
you are right!

Answer 7

thanks
