Answer 1

Ответ:

3,9,*4,58+3,9*5,42​=39

Пошаговое объяснение:

3,9 × 4,58 = 17,862

3,9 × 5,42 = 21,138

17,862 + 21,138 = 39

Answer 2

It looks like you've written a mathematical expression, but there seems to be a comma instead of a decimal point. To make sense of the expression, I'll assume you meant to use decimal points. Here's the expression with decimal points:

3.9 * 4.58 + 3.9 * 5.42

Now, let's calculate the result:

3.9 * 4.58 = 17.862 3.9 * 5.42 = 20.958

Now, add the two results together:

17.862 + 20.958 = 38.82

So, the result of the expression is approximately 38.82.
