Sometimes a logarithm is written without a base, like this: log (100) This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number. Example: log (1000) = log10(1000) = 3. Now, we will use the method called “ proof by contradiction” to show that the product of a non-zero rational number and an irrational number is an irrational number. Let “r” be a non-zero rational number and x be an irrational number. Assume that r= m/n, where m and n are integers, where m≠ 0, and n≠ 0. Assume that rx is rational.Greatest lower bound of some set of numbers is a number which is a lower bound of the set and is bigger or equal to any other lower bound of the set. inf A inf A means greatest lower bound of the set A A. So e.g. inf A = 5 inf A = 5 means greatest lower bound of the set A A is 5 5 . Greatest lower bound is also called infimum. Share. Cite. Follow.In mathematics, we have different symbols.
