# Math Help - simple Maclaurin Series question

1. ## simple Maclaurin Series question

How would i find the Maclaurin Series of f(x)=3^x or for that matter any basic number? I know its simaler to how e^x is found.

2. $e^u = 1 + u + \frac{u^2}{2!} + \frac{u^3}{3!} + ...$

$3^x = e^{\ln{3} \cdot x} = 1 + (\ln{3} \cdot x) + \frac{(\ln{3} \cdot x)^2}{2!} + \frac{(\ln{3} \cdot x)^3}{3!} + ...$

3. Thanks!
