# Math help - Logarthmic functions

I'm a newbie to logs and I need help for the q:

e^(lnx + lny^x)

the symbol ^ means its a power.

It seems to me like you need the normal logarithmic rules to solve this:
$\log_a x^k = k \log_a x$
$\log_a x + \log_a y = log_a xy$
And finally:
$e^{\ln a} = a$
As per TSR rules, I've tried to just give some hints: hopefully you can see how these fit into your question? If not, let me know and I'll get back to you . I hope this helps!

P.S.
Do note that $\ln a = \log_e a$
