Question

27÷3+(19+6) (82-74):2×7 (91-83)×3:4 (8+27):5-7 (27-19)×4+18÷3

Answer 1

Ответ:

Пошаговое объяснение:

27÷3+(19+6)=27÷3+25=9+25=34

(82-74):2×7=8:2*7=4*7=28

(91-83)×3:4=8*3:4=24:4=6

(8+27):5-7=35:5-7=7-7=0

(27-19)×4+18÷3=8*4+18:3==32+6=38

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) to simplify it step by step:

1. Calculate what's inside the parentheses or brackets:

   • Inside the first set of parentheses: (19 + 6) = 25
   • Inside the second set of parentheses: (82 - 74) = 8
   • Inside the third set of parentheses: (91 - 83) = 8
   • Inside the fourth set of parentheses: (8 + 27) = 35

2. Perform the multiplications and divisions from left to right:

   • 27 ÷ 3 = 9
   • 8 ÷ 2 = 4
   • 35 ÷ 4 = 8.75
   • 18 ÷ 3 = 6

3. Now, you can substitute the results back into the original expression:

   9 + 25 * 4 * 8 - 8.75 - 7 * 8 + 6

4. Continue to perform the remaining multiplications and subtractions from left to right:

   • 25 * 4 = 100
   • 7 * 8 = 56

5. Substitute these values back into the expression:

   9 + 100 - 8.75 - 56 + 6

6. Finally, perform the remaining additions and subtractions:

   9 + 100 - 8.75 - 56 + 6 = 50.25

So, the final result of the expression is approximately 50.25.
