Please solve the following math problems:

title: Activities Lesson Review: Euler' s theorem. Please answer the question below. They ask you to summarise the class activities, referring to any learning evidence that you may provide, if necessary. The learning evidence can consist of your work on activities, (as well as notes taken during classes). As a rule of thumb, your summary should be half a page to one page long each {not including evidence). Your answers should be similar to your answers to the nal section {Putting it all together) of each activity. The task is worth up to 3 marks. Your answer should relate to the questions in the activities, and the discussions that happened in class. Note that these questions do not refer to the content of the modules - just explaining how to apply the Euclidean algorithm, for example, is cit-topic in this task (and has already been assessed in the Number Theory Lesson Review). Question 1 Explain the proof of Euler's theorem on Euler paths and circuits using your answers to Tasks 30-36 of the activity. \f\f
