Answer:
Explanation:
The given expression is (-√9 + √-4).
Now, let's simplify each term separately:
√9 is equal to 3, since the square root of 9 is 3.
√-4 is an imaginary number since the square root of -4 is not a real number. We can write it as 2i, where i represents the imaginary unit.
Therefore, the expression (-√9 + √-4) simplifies to (-3 + 2i).
So, the equivalent expressions to (-√9 + √-4) are -3 + 2i
