Let's break down the provided code step by step:
1. The code imports the `math` module.
2. It then calculates `num` using `math.pow(4, 3)`.
- `math.pow(4, 3)` computes \( 4^3 \) which is \( 64.0 \) (as `math.pow` returns a float).
3. Next, the modulo operation `num % 9` is performed.
- Here, \( 64.0 \mod 9 \) is calculated. To do this, we find out how much 64 is greater than the nearest multiple of 9:
- The multiples of 9 are \( 0, 9, 18, 27, 36, 45, 54, 63, 72, \ldots \)
- The largest multiple of 9 that is less than 64 is 63.
- Therefore, \( 64 - 63 = 1 \).
- Thus, \( 64.0 \mod 9 = 1.0 \).
4. Finally, `print(num % 9)` is executed, which will print `1.0`.
Hence, the output of the code will be:
```
1.0
```
