a question i couldnt get the right answer to:(adsbygoogle = window.adsbygoogle || []).push({});

Differentiate

1. y= 3^x (log(3) x)

[3 = base (dont know the right syntax for typing up logs on the web)]

what i have so far:

y = 3^x (ln 3) (log(3) x) + 3^x / xln3

right answer: 3^x (ln 3) + 3^x / xln3

if we apply the product rule, where did the (log(3) x) go?
