Пошаговое объяснение:

2) (-2)³-(-3)³+(-3)²= -8 - (-27) + 9=-8+27+9=36-8=28

Answer 2

Calculation of Expression

To calculate the expression 2 + (-2)³ - (-3)³ + (-3)², we can follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's calculate the values of the individual terms step by step:

1. (-2)³: - The cube of -2 is -8.

2. (-3)³: - The cube of -3 is -27.

3. (-3)²: - The square of -3 is 9.

Now, we can substitute these values into the original expression and perform the calculations:

2 + (-2)³ - (-3)³ + (-3)² = 2 + (-8) - (-27) + 9 = 2 - 8 + 27 + 9 = 30

So, the value of the expression 2 + (-2)³ - (-3)³ + (-3)² is 30.

Conclusion

The value of the given expression 2 + (-2)³ - (-3)³ + (-3)² is 30.
