Question

Решите выражение полностью: 79 · 23 + 21 · 23 - (23 · 123 - 23 · 23)

Answer 1

Ответ: 0

Пошаговое объяснение:

79 * 23 + 21 * 23 = 100 * 23;

23* 123 - 23 * 23 = 100 * 23;

100*23-100*23 = 0

Answer 2

79*23 + 21*23 - (23*123 - 23*23) = 1817 + 483 - (2829-529) = 2300 - 2300 = 0

Answer 3

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

1. Calculate the products within the parentheses first: 23 · 123 = 2829 23 · 23 = 529

2. Now, calculate the expression within the parentheses: (23 · 123 - 23 · 23) = (2829 - 529) = 2300

3. Next, perform the multiplications and additions outside the parentheses: 79 · 23 = 1817 21 · 23 = 483

4. Finally, perform the additions and subtractions: 79 · 23 + 21 · 23 - (23 · 123 - 23 · 23) = 1817 + 483 - 2300 = 0

So, the result of the expression is 0.
