A radioactive sample has an activity of `4xx10^7` Ci. Express its activity in .becqueral. and .rutherford..

Explanation

To solve the problem of converting the activity of a radioactive sample from curies (Ci) to becquerels (Bq) and rutherfords (Rd), we will follow these steps:

### Step 1: Understand the given data
The activity of the radioactive sample is given as:
\[ A = 4 \times 10^7 \text{ Ci} \]
