What other irrational numbers are there besides pi?
e, the base of the natural logarithm, is an important irrational constant. Any positive integer that isn't a perfect square will have an irrational square root. Any non-repeating decimal that goes on forever is irrational. 1.101001000100001...(add an extra zero between each pair of ones). If you study number theory and the transfinites, irrational numbers are actually far more common than rationals because they are defined by a higher infinity. If you were to pick a number completely at random, it would be irrational because the probability of it being rational is zero.
What are some random facts about the number 51?
It is an integer because it is a whole number It is a rational number that can be expressed as a fraction It is an odd number Its prime factors are 3 and 17 It is 51/1 as an improper fraction It is 51.0 as a decimal Its square root is an irrational number that can't be expressed as a fraction It is LI expressed in Roman numerals
If a 4 digit number is chosen at random what is the probability that the product of the digits is 12?
49/9000
One number is chosen at random from the whole numbers 1 to 100 inclusiveWhat is the probability that the number is not prime?
3 out of 4
Why repeating decimals happen?
A repeating decimal is any rational number whose decimal representation does not terminate after a given number of digits. As only a very small quantity of the rational numbers terminate in their decimal representation, practically any rational number picked at random will be a repeating decimal.
