6. It doesn't matter how long the number is. A one with a bunch of zeroes, subtract five anywhere in the middle will leave a one, a five, and a bunch of zeroes.
Armstrong numbers are the sum of their own digits to the power of the number of digits.

You calculate this as follows.Call your number x.x = 0.325325325...Multiply it by 1000 - this is 10 to the power 3, where 3 is the number of digits that repeat.Now subtract 1000x minus x:1000x = 325.325325325...x = 0.325325325...----------------------------------999x = 325Solving for x, x = 325 / 999.

Expressed as a proper fraction in its simplest form, -2-6 = -1/64 or minus one sixty-fourth. Expressed as a decimal, this is equal to -0.015625.
This number cannot exist, because in base 6 the digits used are {0,1,2,3,4,5}, unless you're wanting 21610 expressed in base six. If that's the case then it is 10006, since 216 is 6^3 it will be 1 times 6 to the 3rd power, and all the other digits are zero.
There are 3 significant digits; the number can be expressed as 9.09 times ten to the minus third power.
10 to the minus 7 power (10^-7)
9-2 = 1/92 = 1/81

The rule is to move the digits of the number the same number of columns as the power of ten right in the place value table. As this is not easy with pencil and paper, the rule is usually expressed in how it affects the position of the decimal point in the number, which is: Move the decimal point the same number of digits as the power of ten to the left, inserting zeros if necessary. If the decimal point is not showing it is "hiding" after the units (or ones) digit at the right hand end.
* Remove trailing zeros now you have 789 Insert a decimal point between the first and second digits now you have 7.89 Count the digits to the left of the first digit in this case 10 Multiply the number in step 2 by 10 raised to the power the number in the third step So you get 7.89 X 1010 It can also be expressed as 7.89E10
