Answer 2

To evaluate this expression, we need to apply the order of operations (also known as PEMDAS) which is:

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's start by simplifying each term of the expression:

• (3,4-5,6)*3 = (3,-1)*3 = (9,-3)
• (3,4+5,6)*4 = (3,9)*4 = (12,36)

Now we can substitute these values back into the original expression:

(3,4-5,6)*3+(3,4+5,6)*4 = (9,-3) + (12,36)

To add these two vectors, we add their corresponding components:

(9,-3) + (12,36) = (9+12,-3+36) = (21,33)

Therefore, the final result of the expression is (21,33).
