Question

Сума 128 + 821 не делица на 2

Answer 1

Ответ:

Сумма не делится нацело на 2, так как оканчивается нечетной цифрой

(8+1=9).

Пошаговое объяснение:

Answer 2

That statement is incorrect. The sum of 128 + 821 is 949, and 949 is divisible by 2. In fact, any even number added to another even number will always result in an even number, which is divisible by 2.

To clarify further, if you have two even numbers, let's say A and B:

A = 2k (where k is an integer) B = 2m (where m is an integer)

Then the sum of A + B will be:

A + B = 2k + 2m = 2(k + m)

As you can see, the sum is a multiple of 2, which means it is divisible by 2.
