1. The problem asks us to classify each expression as either "Equivalent to a natural number" or "Not equivalent to a natural number." A natural number is a positive integer starting from 1, 2, 3, and so on.
2. The expressions given are:
- $4^3$
- $(-2)^3$
- $\sqrt[3]{-8}$
- $(-5)^2$
3. We already know $4^3 = 64$, which is a natural number.
4. Calculate $(-2)^3$:
$$(-2)^3 = (-2) \times (-2) \times (-2) = 4 \times (-2) = -8$$
Since $-8$ is negative, it is not a natural number.
5. Calculate $\sqrt[3]{-8}$ (the cube root of $-8$):
$$\sqrt[3]{-8} = -2$$
Because $-2$ is negative, it is not a natural number.
6. Calculate $(-5)^2$:
$$(-5)^2 = (-5) \times (-5) = 25$$
Since $25$ is positive, it is a natural number.
7. Final classification:
- Equivalent to a natural number: $4^3 = 64$, $(-5)^2 = 25$
- Not equivalent to a natural number: $(-2)^3 = -8$, $\sqrt[3]{-8} = -2$
Therefore, the expressions $4^3$ and $(-5)^2$ go in the "Equivalent to a natural number" column, and $(-2)^3$ and $\sqrt[3]{-8}$ go in the "Not equivalent to a natural number" column.
