Question

Help me please!!!! Довести что 723^2+277^3 делится на 1000 (нужно ещё объяснить)

Answer 1

Так как 3*3=9, 7^3=343, то 9+3=12, последние числа. Так что не делится)

Answer 2

Task: Prove that 723^2 + 277^3 is divisible by 1000

To prove that the expression 723^2 + 277^3 is divisible by 1000, we need to show that the result of this expression leaves no remainder when divided by 1000.

Let's calculate the expression and check if it is divisible by 1000.

First, let's calculate 723^2: 723^2 = 523,729

Next, let's calculate 277^3: 277^3 = 21,287,633

Now, let's add these two results together: 523,729 + 21,287,633 = 21,811,362

To determine if 21,811,362 is divisible by 1000, we need to check if the last three digits are 000.

The last three digits of 21,811,362 are 362, which is not equal to 000. Therefore, we can conclude that 723^2 + 277^3 is not divisible by 1000.
