The expression \( a^3 - 3 \) simplifies as follows:

1. \( a^3 \) means \( a \) raised to the power of 3, which is \( a \times a \times a \).
2. After calculating \( a^3 \), you subtract 3 from it.

The result of the expression depends on the value of \( a \). If you provide a specific value for \( a \), I can compute the exact result.

Do you want to evaluate it for a specific \( a \), or should I leave it in its general form \( a^3 - 3 \)?
