Answer 1

 2,856:1,4+3,45•0,8=4,8
2,856:1,4=2,04
3,45*0,8=2,76
2,04+2,76=4,8
Взаимно простые числа, это числа которые делятся только на единицу и само на себя -107 и 871
а вот , чтобы не повторялось я не могу.

Answer 2

Calculation: 2,856:1,4 + 3,45•0,8

To calculate the expression 2,856:1,4 + 3,45•0,8, we need to follow the order of operations (PEMDAS/BODMAS).

First, let's calculate 2,856 divided by 1,4. The result is approximately 2,040.

Next, let's calculate 3,45 multiplied by 0,8. The result is approximately 2,760.

Finally, let's add the two results together: 2,040 + 2,760 = 4,800.

Therefore, the value of the expression 2,856:1,4 + 3,45•0,8 is approximately 4,800.

Creating two three-digit mutually prime numbers using the digits 0, 1, 7, 8

To create two three-digit mutually prime numbers using the digits 0, 1, 7, 8, we need to ensure that the two numbers have no common factors other than 1.

Let's start by considering the hundreds digit. Since we want the numbers to be mutually prime, we cannot use 0 as the hundreds digit because any number with 0 as the hundreds digit is divisible by 10 and therefore not mutually prime with any other number.

Let's consider the possible combinations for the hundreds digit: 1 and 7.

For the first number, let's choose 1 as the hundreds digit. Now we have two digits left: 7 and 8.

For the tens digit, we can choose any of the remaining digits: 7 or 8.

For the units digit, we can choose any of the remaining digits: 7 or 8.

Therefore, one possible three-digit number is 178.

For the second number, let's choose 7 as the hundreds digit. Now we have two digits left: 1 and 8.

For the tens digit, we can choose any of the remaining digits: 1 or 8.

For the units digit, we can choose any of the remaining digits: 1 or 8.

Therefore, another possible three-digit number is 718.

Both 178 and 718 are three-digit numbers created using the digits 0, 1, 7, 8, and they are mutually prime because they have no common factors other than 1.

Therefore, two three-digit mutually prime numbers created using the digits 0, 1, 7, 8 are 178 and 718.
