Logistic Regression: Different Formulas between Courses?

New to statistical and machine learning and taking some online courses.

I am trying to understand logistic regression in more details, and noticed a difference in the formula between the Andrew Ng course and the Stanford statistical learning course. Below I post a link image to both formulas. So the numerator is different. I must be missing smthg as I am a noob in this:

and $$h_\theta(x)=\frac{1}{1+e^{-\theta^\top x}}.$$
