Answer 2

To solve this expression, let's break it down step by step:

Expression: (-3, 25+3, 4) × (-6, 25) + (-2+0, 75) ÷ (0, 8)

1. Simplify the terms inside parentheses:

   • The first set of parentheses contains a comma-separated list of numbers: (-3, 25+3, 4)
     • This simplifies to (-3, 28, 4)
   • The second set of parentheses contains a single number: (-6, 25)

2. Replace the comma-separated lists with their final values:

   • (-3, 28, 4) × (-6, 25) + (-2+0, 75) ÷ (0, 8) becomes
   • (-3) × (-6) + (0, 75) ÷ (0, 8)

3. Perform the multiplications and divisions:

   • (-3) × (-6) = 18
   • (0, 75) ÷ (0, 8) is undefined because division by zero is not defined in mathematics.

Since the division by zero is undefined, the expression as a whole is also undefined.

In summary, the solution is undefined due to division by zero in the original expression.
