Answer 2

Ответ:

Пошаговое объяснение:

a) a-(-b-(c+d-m)-n+k)=a-(-b+(-c-d+m)-n+k)=a-(-b-c-d+m-n+k)=a-(-b-c-d+m-n+k) =a+(+b+c+d-m+n-k)=a+b+c+d-m+n-k

б) a-(b-c+(d-m+n)+k) =a-(b-c-d-m+n+k) =a+(-b+c+d+m-n-k)=a-b+c+d+m-n-k

в)a+(-b+c-(d-m+n)+k)​ =a+(-b+c+(-d+m-n)+k)​ =a+(-b+c-d+m-n+k) =a-b+c-d+m-n+k

Answer 3

A) a-(-b-(c+d-m)-n+k

To simplify the expression a-(-b-(c+d-m)-n+k), we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Let's break down the expression step by step:

1. Start with the innermost parentheses: c+d-m. This can be simplified to c + d - m.

2. Next, we have -b - (c + d - m) - n + k. We can simplify this by distributing the negative sign to each term inside the parentheses: -b - c - d + m - n + k.

3. Finally, we have a - (-b - c - d + m - n + k). To simplify this, we can distribute the negative sign to each term inside the parentheses: a + b + c + d - m + n - k.

Therefore, the expression a-(-b-(c+d-m)-n+k) simplifies to a + b + c + d - m + n - k.

B) a-(b-c+(d-m+n)+k)

To simplify the expression a-(b-c+(d-m+n)+k), we can follow the order of operations.

Let's break down the expression step by step:

1. Start with the innermost parentheses: d-m+n. This can be simplified to d - m + n.

2. Next, we have b - c + (d - m + n) + k. We can simplify this by adding the terms inside the parentheses: b - c + d - m + n + k.

3. Finally, we have a - (b - c + d - m + n + k). To simplify this, we can distribute the negative sign to each term inside the parentheses: a - b + c - d + m - n - k.

Therefore, the expression a-(b-c+(d-m+n)+k) simplifies to a - b + c - d + m - n - k.

C) a+(-b+c-(d-m+n)+k)

To simplify the expression a+(-b+c-(d-m+n)+k), we can follow the order of operations.

Let's break down the expression step by step:

1. Start with the innermost parentheses: d-m+n. This can be simplified to d - m + n.

2. Next, we have -b + c - (d - m + n) + k. We can simplify this by subtracting the terms inside the parentheses: -b + c - d + m - n + k.

3. Finally, we have a + (-b + c - d + m - n + k). This expression does not require any further simplification.

Therefore, the expression a+(-b+c-(d-m+n)+k) simplifies to a - b + c - d + m - n + k.
