Answer:
6i-4
Explanation:
To simplify the expression 4i+(8-3i) - 12+√-25, you can start by combining like terms.
First, you can combine the terms 4i and -3i to get 1i. You can also combine the constants 8 and -12 to get -4.
So, the expression becomes 1i - 4 + √-25.
Next, you can simplify the square root. √-25 is the same as √(-25) which is the same as √(5*-5), which is the same as 5√(-1). √(-1) is equal to i, so 5√(-1) is equal to 5i.
Therefore, the final simplified form of the expression is 1i - 4 + 5i, which is equal to 6i - 4.
