Find numerically greatest term is the expansion of `(3-5x)^11 "when " x=1/5`

Explanation

To find the numerically greatest term in the expansion of \((3 - 5x)^{11}\) when \(x = \frac{1}{5}\), we can follow these steps:

### Step 1: Identify the parameters
In the binomial expansion of \((a + b)^n\), we have:
- \(n = 11\)
- \(a = 3\)
- \(b = -5x\)
