How many positive integers

< 1, 000, 000

contain the digit

https://math.stackexchange.com/q/669737

I'm afraid you've miscounted. In this case, it would be better to count indirectly, by finding the numbers that don't have the digit

in them, then subtracting these from the total. First, let's ...

Prove that every positive integer having

3^{m}

equal digits is divisible by

3^{m}

https://math.stackexchange.com/questions/1964834/prove-that-every-positive-integer-having-3m-equal-digits-is-divisible-by-3m

We will proceed by induction on

m

m = 0

d

be any digit from 1 to 9. We need to prove this statement for all

m \geq 0

S (m) : 3^{m} ∣ 3^{m} d d d \dots d d d

S (0)

If we select a random integer number of the set

[1000000]

what is the probability of the number selected contains the digit

Sum of super exponentiation

https://math.stackexchange.com/questions/1346703/sum-of-super-exponentiation

q = 5000000003

p = 2 q + 1

1 0^{18} = 1999999992 * (q - 1) + 16

f (x, 1 0^{18}) = 1999999992 * (x^{2} + x^{4} + . . . + x^{2 (q - 1)}) + (x^{2^{1}} + x^{2^{2}} + . . . + x^{2^{16}})

Now we can use the fact that

Does “arbitrarily small” mean very close to zero or very negative?

https://math.stackexchange.com/q/900371

Traditionally, it's the first one: "arbitrarily small" means "small in magnitude", close to zero. I see the logic behind the second interpretation, but numbers like

- 1 0^{9}

are normally thought of as ...

Find the number of bytes that begin with 10 or end with 01.

https://math.stackexchange.com/questions/442455/find-the-number-of-bytes-that-begin-with-10-or-end-with-01

You forgot numbers that start with 10 and end with 01 - 10xxxx01 - it give you 16 numbers. 96 + 16 = 112
