Answer 3

I can help you with your math problem. Here is the detailed solution:

The given expression is $$2 \cdot (-5)^2 - 6 \cdot 0.5$$

To simplify it, we need to follow the order of operations: parentheses, exponents, multiplication, and subtraction.

First, we evaluate the parentheses. Since there is only one term inside, we do not need to do anything. We get $$2 \cdot (-5)^2 - 6 \cdot 0.5$$

Next, we evaluate the exponents. We raise -5 to the power of 2, which gives 25. We get $$2 \cdot 25 - 6 \cdot 0.5$$

Then, we evaluate the multiplication. We multiply 2 by 25, which gives 50. We also multiply 6 by 0.5, which gives 3. We get $$50 - 3$$

Finally, we evaluate the subtraction. We subtract 3 from 50, which gives 47. We get $$47$$

Therefore, the value of the expression is $$47$$

I hope this helps. If you have any other math questions, feel free to ask me.Ответь+подробно.++Обчисліть+значення+виразу+2+•(-5)2+-6•0,5+
