Question

Выполните действия. (-5,8)в квадрате-14,28 умножить (-5/7)-30.04

Answer 1

(-29/5)^2-357/25•(-5/7)-751/25=-841/25+51/5-751/25=-1337/25

Answer 2

(-5,8)² - 14,28 * (-5/7) - 30,04 = 
= 33,64 + 1428/100 * 5/7 - 30,04 = 
= 33,64 - 30,04 + 204/20 = 
= 3,6 - 10,2 = 
= -6,6

Answer 3

I can help you with math problems. Here is the solution to your query:

To perform the operations, we need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction.

First, we evaluate the expression inside the parentheses: $$(-5,8)$$

This is a decimal number, which means we use a dot instead of a comma: $$-5.8$$

Next, we evaluate the exponent: $$(-5.8)^2$$

To square a number, we multiply it by itself: $$(-5.8)\times(-5.8)$$

Using a calculator, we get: $$33.64$$

Then, we evaluate the multiplication: $$-14.28\times(-5/7)$$

To multiply fractions, we multiply the numerators and the denominators: $$\frac{-14.28\times(-5)}{7}$$

Using a calculator, we get: $$10.2$$

Finally, we evaluate the subtraction: $$33.64-10.2-30.04$$

Using a calculator, we get: $$-6.6$$

Therefore, the final answer is: $$-6.6$$Ответь+подробно.+Выполните+действия.+(-5,8)в+квадрате-14,28+умножить+(-5/7)-30.04
