Question

2) a-(6-(c-d));4) a-(b+(c-(d - k))).​

Answer 1

2)a-(6-(c-d))=a-6+c-d

4)a-(b+(c-(d-k)))=a-b-c+d-k

Answer 2

It looks like you've provided two arithmetic expressions. I can help you simplify or evaluate them if you'd like. Let's take a look at each expression:

1. a - (6 - (c - d))

2. a - (b + (c - (d - k)))

If you want me to simplify or evaluate them, please provide the values of the variables a, b, c, d, and k. If you're looking for something specific, feel free to clarify your request.
