A radioactive sample with half-life 2 days has initial activity `32mu Ci`. What will be its activity after 8 days?

Explanation

To solve the problem of determining the activity of a radioactive sample after a certain period, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Given Values:**
- Initial activity, \( A_0 = 32 \, \mu \text{Ci} \)
- Half-life, \( T_{1/2} = 2 \, \text{days} \)
- Time elapsed, \( t = 8 \, \text{days} \)
