WebbWe will discuss here about the different Laws of Indices. If a, b are real numbers (>0, ≠ 1) and m, n are real numbers, following properties hold true. (i) a m × a n = a m + n Webb00:00 In this video, you’ll practice list indexing and slicing. The elements of a list can be accessed by an index. To do that, you name the list, and then inside of a pair of square brackets you use an index number, like what I’m showing right here.. 00:17 That allows access to individual elements within the list. The indexing for the list is zero-based.
