Hello all

If [tex]y = e^3^\ln^(x^2)[/tex] find [tex]\frac {dy}{dx}[/tex]

So [tex]\frac {dy}{dx} =(3 (\frac {1}{x^2}) \* 2x e^3^\ln^(x^2)[/tex]

So the simplified answer is: [tex]\frac {6}{x} e^3^\ln^(x^2)[/tex]

Is this correct? IS there any other way of expressing the answer?

Thanks

Use your log rules.

[tex]e^{3 \ln x^2} \equiv e^{\ln x^6} \equiv x^6[/tex]

oh i see

So derivative would be [tex]6x^5[/tex]

didn't catch that

thanks
 
Pretty much anytime you see e and ln stuck together like that, it means your teacher is trying to get you to use log rules.
