Question

find all the critical points

Answer 1

\[f(x)=x \ln(8x) \rightarrow f'=x\frac{ 8 }{ 8x }+\ln(8x) \rightarrow f'=0 \rightarrow \ln(8x)=-1\rightarrow 8x=e^{-1?}\]

Answer 2

i dont understand where you got ln(8x)=-1

Answer 3

@amoodarya

Answer 4

f' = 1 + ln (8x)\(\rightarrow\) ln(8x)=-1

Answer 5

for f'(x) i got ln8x+1/8x

Answer 6

sorry +1/8
