hi everyone new to the forum here.(adsbygoogle = window.adsbygoogle || []).push({});

here's my problem. I have to tell whether a given expression is a polynomial in x or not, and if so give its degree.

I've figured out 4 of the 5 but i'm stuck on the third one

2^x + 3x

since 2 is being raised to x and 3 is being multiplied by x i'm completely confused on how to determine if it is or not and what the degree would be if it has one

please help
