Question

4,4² − 2 ⋅ 4,4 ⋅ 0,5 + 0,5² = ; (4,4 − 0,5)² = ; (4,4 − 0,5) ⋅ (4,4 + 0,5) = решите пожалуйста)

Answer 1

Решение:

1) 4,4² − 2 ⋅ 4,4 ⋅ 0,5 + 0,5² = (4,4 - 0,5)² = 3,9² = 15,21;

2) (4,4 − 0,5)² = 3,9² = 15,21;

3) (4,4 − 0,5) ⋅ (4,4 + 0,5) = 4,4² - 0,5² = 19,36 - 0,25 = 19,11.

Answer 2

Let's solve the given expressions step by step:

1. 4.4² − 2 ⋅ 4.4 ⋅ 0.5 + 0.5²:

First, calculate the individual terms:

• 4.4² = 4.4 * 4.4 = 19.36
• 2 ⋅ 4.4 ⋅ 0.5 = 4.4
• 0.5² = 0.5 * 0.5 = 0.25

Now, substitute these values into the expression: 4.4² − 2 ⋅ 4.4 ⋅ 0.5 + 0.5² = 19.36 - 4.4 + 0.25 = 15.21

2. (4.4 − 0.5)²:

First, perform the subtraction inside the parentheses: 4.4 - 0.5 = 3.9

Now, calculate the square of the result: (4.4 − 0.5)² = 3.9 * 3.9 = 15.21

3. (4.4 − 0.5) ⋅ (4.4 + 0.5):

First, perform the subtraction inside the parentheses: 4.4 - 0.5 = 3.9 4.4 + 0.5 = 4.9

Now, calculate the product of the two results: (4.4 − 0.5) ⋅ (4.4 + 0.5) = 3.9 * 4.9 = 19.11

So, the solutions to the given expressions are:

1. 4.4² − 2 ⋅ 4.4 ⋅ 0.5 + 0.5² = 15.21
2. (4.4 − 0.5)² = 15.21
3. (4.4 − 0.5) ⋅ (4.4 + 0.5) = 19.11
