Why does mathematica give wrong answer for the derivative?

Question

I am trying to find the derivative of

3^x

The derivative should be

ln (3) 3^x

However, the Mathematica gives me the answer as

Log[3] 3^x

I am using Mathematica 11.2 Student Edition. Can somebody help me why this is happening?

Answer 1

The default base for Log in Mathematica is e, so Log[3] is the natural log of 3, or ln(3). It means the same thing.
