Which is the smallest Armstrong number?
An Armstrong number is a n -digit number that is equal to the sum of each of its digits taken to the n th power. For example, 153 is an armstrong number because 153 = 1³ + 5³ + 3³. Other than the numbers 1 through 9, it is the smallest Armstrong number; there are none with two digits.
How is Armstrong number calculated?
An Armstrong number, also known as narcissistic number, is a number that is equal to the sum of the cubes of its own digits. For example, 370 is an Armstrong number since 370 = 3*3*3 + 7*7*7 + 0*0*0 .
What are Armstrong numbers between 1 to 1000?
In the range 0 to 999 there exists six Armstrong numbers- 0, 1, 153, 370, 371 and 407 . In the range 1000 to 9999 there are three Armstrong numbers- 1634, 8208 and 9474 .
How many 2 digits are there?
90
The total number of two digit numbers is 90. From 1 to 99 there are 99 numbers, out of which there are 9 one-digit numbers, i.e., 1, 2, 3, 4, 5, 6, 7, 8 and 9. If one digit numbers are subtracted from 99 we get 90 two-digit numbers.

The number 10 has two digits (1 and 0) so this is an example of 2 figures.
What is the value of Armstrong number 2*1?
An Armstrong number is a n digit number, which is equal to the sum of the nth powers of its digits. 2*1=2 which is equals to number (2) itself so on for all the 1 digit numbers (1-9).
