NettetAnswer (1 of 4): Expanding on Roman Andronov’s answer, let’s try and answer a much more general question: > For each natural number n, find the smallest natural number \mu(n) with the property that among any \mu(n) consecutive natural numbers there exists at least one whose sum of (decimal) dig... NettetEvery positive integer n can be expressed as a sum of four squares. Theorem (Two-Square Theorem) A positive integer n can be written as a sum of two squares if and only if in the prime factorisation of n every prime q 3 (mod 4) appears with an even exponent. Why is the three-square theorem much harder to prove? No composition law.

If we have a terminating decimal, we can use Fraction to Decimal and Decimal to Fraction converter. In the case of a repeating decimal, the calculation becomes a bit trickier. av31-b1 ダンレイ
