A list of elements, separated by commas, enclosed in curly braces. Example: {3, 5, 7} is the set of single-digit odd prime numbers. Tricky Example: { { }, {3}, {5}, {7}, {3,5}, {3,7}, {5,7}, {3,5,7} } is the set of subsets of the set of single-digit odd prime numbers. Notice that every element of this set is itself a set. The roster notation allows the use of nested curly-braces to describe sets which have other sets as elements. Infinite set in roster notation: {1, 2, 3, ...} is the set of positive integers. The first few elements illustrate the pattern, and the ellipsis (three dots) indicate that the pattern continues indefinitely.

roster method is just like listing method
The exponential notation and standard notation for 2x2x2x2x2 is:2532
It is just the number written out as we normally write it.Example #1: for the number 725:Standard Notation = 725Scientific Notation = 7.25 x 102Expanded Notation = 700 + 20 + 5Number And Word Notation = 7.25 hundredExample #2: for the number 365.23:Standard Notation = 365.23Scientific Notation = 3.6523 x 102Expanded Notation = 300 + 60 + 5 + .2 + .03Number And Word Notation = 3.6523 hundred
