Question

(2-½)²-3²-(1-3³)-1,5²=​

Answer 1

Ответ:

-1

Объяснение:

1,5²-3²-(1-9)-1,5²=-3²-(-8)=-9+8=-1

Answer 2

Решение:

$\Big (2 - \dfrac{1}{2} \Big )^2 - 3^2 - (1 - 3^3)-1.5^2 =\\ \\=1.5^2 + 3^2 - 1 +3^2 - 1.5^2 =\\ \\=(1.5^2 - 1.5^2) + (3^2+3^2) - 1 =\\ \\=-1$

Answer 3

Let's break down the expression step by step:

1. First, calculate (2 - ½)²: (2 - ½)² = (1.5)² = 2.25

2. Next, calculate 3²: 3² = 9

3. Now, calculate (1 - 3³): 3³ = 3 * 3 * 3 = 27 1 - 27 = -26

4. Finally, calculate 1.5²: 1.5² = 2.25

Now, let's put it all together:

(2 - ½)² - 3² - (1 - 3³) - 1.5² = 2.25 - 9 - (-26) - 2.25

Now, let's perform the subtraction:

2.25 - 9 + 26 - 2.25

Combine like terms:

(2.25 - 2.25) + 26 - 9

Now, subtract 2.25 from itself:

0 + 26 - 9

Finally, subtract 9 from 26:

26 - 9 = 17

So, the value of the expression is 17.
