Answer 1

Вот и решение легко и просто)

Answer 2

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

1. Parentheses/Brackets
2. Exponents/Orders (i.e., powers and square roots)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's simplify the expression step by step:

1. -0.7 * (-10)^2 + 90^2

2. (-10)^2 means raising -10 to the power of 2, which gives us 100.

3. -0.7 * 100 + 90^2

4. Now, let's calculate 90^2, which is 90 multiplied by itself: 90 * 90 = 8100.

5. -0.7 * 100 + 8100

6. Now, perform the multiplication: -0.7 * 100 = -70.

7. -70 + 8100

8. Finally, add the two values: -70 + 8100 = 8030.

So, the simplified expression is 8030.
