Question

45:5:3+9*3-21:3+72:8*4

Answer 1

Ответ:

Ответ: 59

Пошаговое объяснение:

45:5:3=3

9*3=27

72:8*4=36

36+27+3=59

Answer 2

45 : 5 : 3 + 9 * 3 - 21 : 3 + 72 : 8 * 4 = 59

1) 45 : 5 = 9

2) 9 : 3 = 3

3) 9 * 3 = 27

4) 21 : 3 = 7

5) 72 : 8 = 9

6) 9 * 4 = 36

7) 3 + 27 = 30

8) 30 - 7 = 23

9) 23 + 36 = 59

Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, you should first perform the multiplication and division from left to right and then perform the addition and subtraction from left to right:

1. 45 ÷ 5 = 9
2. 21 ÷ 3 = 7
3. 9 * 3 = 27
4. 72 ÷ 8 = 9

Now you have simplified the expression to:

9 + 27 - 7 + 9 * 4

Next, continue with the addition and subtraction:

9 + 27 = 36 36 - 7 = 29 9 * 4 = 36

Finally, perform the remaining addition:

29 + 36 = 65

So, the result of the expression is 65.
