Question

9×(0,001+0,999)×(6×0,7-3)+7​

Answer 1

Ответ:

9×1(4,2-3)+7=9×1,2+7=10,8+7=17,8

Answer 2

Let's solve the expression step by step:

1. First, calculate the expression within the parentheses: 0.001 + 0.999 = 1

2. Next, multiply the result by 9: 9 × 1 = 9

3. Now, calculate the expression within the next set of parentheses: 6 × 0.7 - 3 = 4.2 - 3 = 1.2

4. Finally, multiply the previous result by 9 and add 7: 9 × 1.2 + 7 = 10.8 + 7 = 17.8

So, the final result of the expression is 17.8.
