A sound produced by one musical instruments is 20dB more intense as compared to the sound by another instrument. What are their relative powers?

Explanation

To solve the problem of determining the relative powers of two musical instruments based on their sound intensity levels, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship Between Intensity and Decibels**:
The intensity level in decibels (dB) is given by the formula:
\[
L = 10 \log_{10} \left( \frac{I}{I_0} \right)
