To solve the problem shown in the figure attached, you must apply the proccedure shown below:
1. You have the following complex number given in the exercise:
√(-36)+10
2. By definition, you have that:
i=√(-1)
3. Then:
√(36)=6
√(-36)=6√(-1)=6i
3. Therefore, you have the correct notation for the complex number √(-36)+10 is:
10+6i
The answer is the option A:
A. 10+6i
