Write the value of `sqrt(-25)xxsqrt(-9)dot`

Explanation

To solve the expression \( \sqrt{-25} \times \sqrt{-9} \), we will follow these steps:

### Step 1: Rewrite the square roots of negative numbers
We know that \( \sqrt{-a} = i \sqrt{a} \), where \( i \) is the imaginary unit defined as \( i = \sqrt{-1} \).

So, we can rewrite:
\[
\sqrt{-25} = \sqrt{-1 \times 25} = \sqrt{-1} \times \sqrt{25} = i \times 5 = 5i
