Question

1)a +(-a) + a 2)b+(-b)+b+(-b)+(-b)​

Answer 1

Ответ:

1) а+(-а)+а=а-а+а=а

2)b+(-b)+b+(-b)+(-b)=b-b+b-b-b= -b

Answer 2

1. In the expression "a + (-a) + a," we have three terms: "a," "-a," and "a." The term "-a" is the additive inverse of "a," which means it cancels out the original value when added together. Therefore, we can simplify the expression as follows:

a + (-a) + a = a + (-a) + a + (-a) = 2a + (-2a) = 0.

So, the simplified expression is 0.

2. In the expression "b + (-b) + b + (-b) + (-b)," we have five terms: "b," "-b," "b," "-b," and "-b." Similar to the previous example, the additive inverse of "b" is "-b," which cancels out the original value when added together. We can simplify the expression as follows:

b + (-b) + b + (-b) + (-b) = b + (-b) + b + (-b) + (-b) + (-b) = 2b + (-3b) = -b.

So, the simplified expression is -b.
