Question

Вычислите наиболее простым способом А)-46*82+36*82= б)-846+39-(48-846)=Заранее огромное спасибо.

Answer 1

А) 82*(36-46)=-820
б) -846+39-48+846=-9
В первом примере выносишь общий множитель
во втором открываешь скобки и сокращаешь число 846

Answer 2

Calculation A: -46 * 82 + 36 * 82

To calculate this expression, we can use the distributive property of multiplication over addition and subtraction. Let's break it down step by step:

- First, we can factor out 82 from both terms: - -46 * 82 + 36 * 82 = (36 - 46) * 82

- Next, we can simplify the expression inside the parentheses: - (36 - 46) * 82 = -10 * 82

- Finally, we can multiply -10 by 82 to get the result: - -10 * 82 = -820

Therefore, the value of A is -820.

Calculation B: -846 + 39 - (48 - 846)

To calculate this expression, we need to follow the order of operations (also known as PEMDAS or BODMAS). Let's break it down step by step:

- First, we can simplify the expression inside the parentheses: - (48 - 846) = -798

- Next, we can substitute the simplified expression back into the original expression: - -846 + 39 - (-798)

- To simplify further, we can remove the double negative by changing the subtraction inside the parentheses to addition: - -846 + 39 + 798

- Finally, we can add the three terms together to get the result: - -846 + 39 + 798 = -9

Therefore, the value of B is -9.
