Пошаговое объяснение:

(-2)³ + (-3)² = -8 + 9 = 1

Answer 2

To evaluate the expression (-2)³ + (-3)² in mathematics, you need to follow the order of operations, which is often represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

1. Start with the exponentiation: (-2)³ means raising -2 to the power of 3. (-2)³ = (-2) * (-2) * (-2) = -8.

2. Next, calculate the exponentiation: (-3)² means raising -3 to the power of 2. (-3)² = (-3) * (-3) = 9.

3. Finally, add the results of the two calculations together: (-2)³ + (-3)² = -8 + 9 = 1.

Therefore, the value of the expression (-2)³ + (-3)² is 1.
