Answer 3

To solve the given expression:

(3, 6×4,25-0,7)×5,9+7,9×0,2

First, let's simplify the expression within the parentheses:

6 × 4.25 - 0.7 = 25.5 - 0.7 = 24.8

Now, let's substitute this value back into the original expression:

(3, 24.8) × 5.9 + 7.9 × 0.2

Now we can perform the multiplication and addition operations:

3 × 24.8 = 74.4

74.4 × 5.9 = 438.96

7.9 × 0.2 = 1.58

Finally, we add the results:

438.96 + 1.58 = 440.54

Therefore, the value of the expression (3, 6×4,25-0,7)×5,9+7,9×0,2 is 440.54.
