Question

( – 5,8)² -14,28-(5/7)-30,04

Answer 1

(-5,8)² = 33,64
33,64 - 14,28 = 19,36
19,36 - 30,04 = -10,68
-10,68 = - 1068/100 = - 534/50 = - 267/25 
Приведём дроби - 267/25 и -5/7 к общему знаменателю 175 и получим в числителе: 
-267*7 - 5*25 = -1869 - 125 = 1994.
Ответ - 1994/175.

Answer 2

It looks like you've provided a mathematical expression. Let's break it down step by step:

1. (–5,8)²: This means "negative 5.8 squared."

   • (-5.8)² = 33.64

2. -14,28: This appears to be a comma-separated number. If you intended it to be subtraction, it would be written as "-14.28".

3. (5/7): This is a fraction, which equals approximately 0.7143 when evaluated.

4. -30,04: Similar to the second point, if you intended this to be subtraction, it should be written as "-30.04".

Now, let's put it all together:

33.64 - 14.28 - 0.7143 - 30.04

Performing the operations in order:

• 33.64 - 14.28 = 19.36
• 19.36 - 0.7143 ≈ 18.6457
• 18.6457 - 30.04 ≈ -11.3943

So, the final result is approximately -11.3943.
