Answer 2

It looks like you're presenting a mathematical expression that involves both multiplication and addition. However, the expression seems a bit unclear due to the use of commas. I'm assuming you meant to use parentheses to indicate grouping. Based on that assumption, I'll simplify the expression for you:

Given expression: 5 * (2 * (1 + 2) + 4 * (5 * (1,2 - 2))

Let's break it down step by step:

1. Inside the innermost parentheses:

   • 1 + 2 = 3
   • 1,2 - 2 doesn't make mathematical sense, so I'm assuming it's a typographical error.

2. 5 * (2 * 3 + 4 * (5 * (1,2 - 2)))

3. Inside the innermost parentheses:

   • (1,2 - 2) doesn't make mathematical sense, so let's assume it's a typographical error.

4. 5 * (2 * 3 + 4 * (5 * (1.2 - 2)))

5. Inside the innermost parentheses:

   • 1.2 - 2 = -0.8

6. 5 * (2 * 3 + 4 * (-0.8))

7. 5 * (6 - 3.2)

8. 5 * 2.8

9. 14

So, based on the simplification of the expression, the result is 14.
