1. Could you please rename "2nd exponential", eg. “powers of 2” or “exponential function with base 2”.

I modified the name, sorry for not adding a comment

This is good, it works, but some comments that the previous reviewer did not address.

1. The name of the operation, Logarithm Add Exponentiations 2, can be made clearer, you can call it "Logaddexp (Base 2)". That is a clearer way of letting the user know that this is done with Base 2.

2. While the name "exponential function with base 2 (y)" is good, it doesn't actually follow Graphbook Naming Conventions. "The first letter of every word needs to be capitalized" when working with composites. So it can be named "Exponential Function With Base 2 (y)" instead. That follows the conventions we have.

Thank you!
