You are a five digit number your digits increase in size from the left Each digit is different your first and fifth digits are square numbers your first and fourth digits are cubed numbers your 2nd?
There are a lot of possibilities. The second digit can be 2 through 6, the third digit can be 3 through 7 as long as it is larger than the second digit. What we have so far: 1 _ _ 89
How long would it take to recite all the known digits of PI?
How long would it take ypu to repeat/recite 50 billion digits or more.
What is the meaning for Armstrong number?
Armstrong numbers are the sum of their own digits to the power of the number of digits. EXAMPLES: 370 = 33 + 73 + 03 = 27 + 343 + 0 = 370 9474 = 94 + 44 + 74 + 44 = 6561 + 256 + 2401 + 256 = 9,474 The largest know Armstrong number (in base 10) is 39 digits long: 115,132,219,018,763,992,565,095,597,973,971,522,401 ( I have no idea how to say that number.)
What is a non integer?
Real Numbers is an alternative to integers. Real Numbers include both rational numbers, such as 42 and −23/129, and irrational numbers, such as pi and the square root of two; or, a real number can be given by an infinite decimal representation, such as 2.4871773339..., where the digits continue in some way; or, the real numbers may be thought of as points on an infinitely long number line. * * * * * Real numbers are not an ALTERNATIVE to non-integers since integers are a subset of real numbers! Otherwise the answer is OK.
Is it true that all decimal numbers rational numbers?
Short answer: yes.Irrational numbers like PI have what are called "decimal expansions." For PI, decimal expansions would be numbers like:3.143.141593.141592653589793238etc.These expansions are, themselves, rational numbers.The thing is, an irrational number has an infinitely long, non-repeating sequence of digits after the decimal point. While these digits can be computer forever to a precision limited only by how much effort a person is willing to put into it, they cannot be exactly represented as decimal numbers. Any possible finite decimal number that you come up with will not be a perfect representation of an irrational number.So strictly speaking, I would say that a decimal number can only ever represent a rational number.
