Question

Помогите пожалуйста умоляю очень надо: Найдите значение выражения: 1)(2,35*6,8-6,793)*0,4+1,3252; 2)3.4*6,5-0,25*(17,6*1,5+3,28) Спасибо заранее))))

Answer 1

1)
1)2,35*6,8=15,98
2)15,98-6,793=9,187
3)9,187*0,4=3,6748
4)3,6748+1,3252=5

2)
1)17,6*1,5=26,4
2)26,4+3,28=29,68
3)3,4*6,5=22,1
4)0,25*29,68=7,42
5)22,1-7,42=14,68

Answer 2

Calculation 1: (2.35 * 6.8 - 6.793) * 0.4 + 1.3252

To find the value of the expression, let's break it down step by step:

1. Multiply 2.35 by 6.8: 2.35 * 6.8 = 15.98. 2. Subtract 6.793 from the result: 15.98 - 6.793 = 9.187. 3. Multiply the result by 0.4: 9.187 * 0.4 = 3.6748. 4. Add 1.3252 to the result: 3.6748 + 1.3252 = 5.

Therefore, the value of the expression (2.35 * 6.8 - 6.793) * 0.4 + 1.3252 is 5.

Calculation 2: 3.4 * 6.5 - 0.25 * (17.6 * 1.5 + 3.28)

Let's calculate the value of the second expression step by step:

1. Multiply 17.6 by 1.5: 17.6 * 1.5 = 26.4. 2. Add 26.4 to 3.28: 26.4 + 3.28 = 29.68. 3. Multiply 0.25 by the result: 0.25 * 29.68 = 7.42. 4. Multiply 3.4 by 6.5: 3.4 * 6.5 = 22.1. 5. Subtract the result from step 3 from the result of step 4: 22.1 - 7.42 = 14.68.

Therefore, the value of the expression 3.4 * 6.5 - 0.25 * (17.6 * 1.5 + 3.28) is 14.68.

I hope this helps! Let me know if you have any further questions.
