Question

(5*6-3*4+48:6)+(82-78)*7-13=. 2) (69-45):3*2+(43-34)*2 разобрать примеры по действиям​

Answer 1

Пошаговое объяснение:

1. 5×6=30

2. 48÷6=8

3. 3×4=12

4. 30-12=18

5. 18+8=26

2. 82-78=4

3. 4×7=28

4. 28-13=15

3 .26+15=41

Answer 2

1. To solve the first expression, we follow the order of operations (also known as PEMDAS) which is:

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Using this rule, we first evaluate the expression inside the parentheses:

(56-34+48:6) = (30 - 12 + 8) = 26

Then we continue with the rest of the expression:

(82-78)7-13 = 47 - 13 = 28 - 13 = 15

Finally, we add the results of the two parts:

26 + 15 = 41

Therefore, the answer to the first expression is 41.

2. For the second expression, we again use the order of operations:

(69-45):32+(43-34)2 = 8:32 + 92

We first evaluate the division:

8:3 = 2.66666667 (rounded to the nearest hundredth)

Then we continue with the multiplication:

2.66666667 * 2 = 5.33333334 (rounded to the nearest hundredth)

Finally, we add the results:

5.33333334 + 9*2 = 5.33333334 + 18 = 23.33333334

Therefore, the answer to the second expression is 23.33333334 (rounded to the nearest hundredth).
