Question

Решение -0,2•(-10)²+55

Answer 1

-0,2*100+55=-20+55=35

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Start with parentheses/brackets.
2. Next, perform any exponentiation.
3. Then, handle multiplication and division from left to right.
4. Finally, perform addition and subtraction from left to right.

Now, let's solve the expression step by step:

Step 1: Deal with parentheses (none in this case). Step 2: Perform any exponentiation.

-10² means -10 raised to the power of 2, which is (-10) * (-10) = 100.

Step 3: Perform multiplication.

-0.2 * 100 = -20

Step 4: Perform addition.

-20 + 55 = 35

So, the solution to the expression -0.2 * (-10)² + 55 is 35.
