Question

9 × (0, 001 + 0, 999) × (6 × 0,7 - 3) -7​

Answer 1

9 * (0, 001 + 0, 999) * (6 * 0,7 - 3) -7​=3,8

0,001+0,999=1

6*0,7=4,2

4,2-3=1,2

9*1=9

9*1,2=10,8

10,8-7=3,8

Answer 2

Ответ:3,8

Пошаговое объяснение:1)0,001+0,999=1

2)6•0,7=4,2

3)4,2-3=1,2

4)9•1=9

5)9•1,2=10,8

6)10,8-7=3,8

Answer 3

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

9 × (0.001 + 0.999) × (6 × 0.7 - 3) - 7

First, let's simplify the innermost parentheses:

0.001 + 0.999 = 1

6 × 0.7 = 4.2

Now we can rewrite the expression:

9 × 1 × (4.2 - 3) - 7

Next, we simplify the remaining parentheses:

4.2 - 3 = 1.2

Now the expression becomes:

9 × 1 × 1.2 - 7

Multiplying:

9 × 1 × 1.2 = 10.8

Substituting the value back into the expression:

10.8 - 7

Finally, subtracting:

10.8 - 7 = 3.8

Therefore, the result of the expression 9 × (0.001 + 0.999) × (6 × 0.7 - 3) - 7 is 3.8.
