Question

7*(16:4)+72:(12-4)*5-28:4

Answer 1

Ответ:

69.

Пошаговое объяснение:

$7\cdot (16:4) +72:(12-4)\cdot5 - 28:7=7\cdot4+72:8\cdot5-4=28+9\cdot5-4=\\\\= 28+45-4=73-4=69.$

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) to calculate the value:

1. Start by evaluating within the parentheses: 16:4 = 4 (Division) 12-4 = 8 (Subtraction)

2. Continue evaluating multiplication and division from left to right: 7 * 4 + 72 / 8 * 5 - 28 / 4

3. Perform multiplications and divisions: 7 * 4 = 28 72 / 8 = 9 9 * 5 = 45 28 / 4 = 7

4. Substitute the results back into the expression: 28 + 45 - 7

5. Perform the remaining addition and subtraction: 28 + 45 - 7 = 66

So, the value of the expression is 66.
