Question

solve the inequality?
x^2e^xlnx>0

Answer 1

\[x^2 e^x lnx >0\]

Answer 2

you only need to solve ln(x)>0

Answer 3

isn't x undefined then?

Answer 4

no...
\[\ln(x)=y \implies e^{y}=x \\ \text{ here we have } y=0 \\ \text{ so we have } e^{0}=x\]

so how do you solve the equation ln(x)=0

Answer 5

like what is the solution

Answer 6

and remember y=ln(x) looks like this:

Answer 7

well e^0 is 1
