Question

Раскройте скобки и найдите значения выражения: (7-2,7)-(-4+2) =?

Answer 1

Ответ:

0.1

Пошаговое объяснение:

7-2,7-4-2

4.3-4.2=0.1

Answer 2

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

1. Start by evaluating what's inside the parentheses/brackets: (7 - 2,7) - (-4 + 2)

The comma in the expression might be a typo, as it doesn't serve a mathematical purpose. Assuming you meant to write a decimal point, the expression becomes:

(7 - 2.7) - (-4 + 2)

2. Continue evaluating the expressions inside the parentheses: (4.3) - (-2)

3. Now, apply the subtraction: 4.3 + 2 = 6.3

So, the value of the expression is 6.3.
