Question

0,54+2(√4, 84) ² -0, 2(√12) ²+3, 45 (3√4, 41) ²-(-2) ³ -0, 4√4, 84х11​

Answer 1

Ответ:

143.0705

Объяснение:

$0.54 + 2 \times 4.84 - 0.2 \times 12 + 3.45 \times 9 \times 4.41 - ( - 8) - \frac{2}{5} \times \sqrt{ \frac{121}{25} } \times 11$

$0.54 + 9.68 - 2.4 + 136.9305 + 8 - \frac{2}{5} \times \frac{11}{5} \times 11$

$0.54 + 9.68 - 2.4 + 136.9305 + 8 - \frac{242}{25}$

$0.54 + 9.68 - 2.4 + 136.9305 + 8 - 9.68$

$= 143.0705$

Answer 2

Let's break down the expression step by step:

1. $0.54 + 2(\sqrt{4.84})^2$
2. $-0.2(\sqrt{12})^2$
3. $3.45(3\sqrt{4.41})^2$
4. $-(-2)^3$
5. $-0.4\sqrt{4.84}\times11$

Now, let's calculate each part:

1. $0.54 + 2(\sqrt{4.84})^2 = 0.54 + 2(2.2)^2 = 0.54 + 2(4.84) = 0.54 + 9.68 = 10.22$

2. $-0.2(\sqrt{12})^2 = -0.2 \times 12 = -2.4$

3. $3.45(3\sqrt{4.41})^2 = 3.45 \times 3 \times (2.1)^2 = 3.45 \times 3 \times 4.41 = 51.4095$

4. $-(-2)^3 = -(-8) = 8$

5. $-0.4\sqrt{4.84}\times11 = -0.4 \times 2.2 \times 11 = -9.68$

Now, let's combine all the results:

$10.22 - 2.4 + 51.4095 + 8 - 9.68$

Adding these values together:

$10.22 - 2.4 + 51.4095 + 8 - 9.68 = 57.5495$

So, the result of the given expression is approximately $57.5495$.
