Solution
Let's simplify the given expression:
Step 1: Simplify the square roots involving negative numbers.
We know that the square root of a negative number involves the imaginary unit , where:
Thus, we can express each square root with a negative number as:
Step 2: Rewrite the expression with imaginary parts.
Substitute these into the expression:
Step 3: Simplify the multiplication.
Multiply the constants and imaginary units separately:
Now multiply the square roots:
Step 4: Combine everything.
The expression simplifies to:
