I am writing to ask for the following question.
1. I heard that people pronounce the brand name "Louis Vuitton" differently. I would like to know how to pronounce this word. Dose someone know how to pronounce it or somewhere I could get the answer?
2. How to say this formula 6.02 X 10 -23 (this -23 should be put on the right top corner of 10. Could it be negative squire 23).
