sorry I don't understand the way its written
Answer:
-6±3i√2
Step-by-step explanation:
First we need to simplify the radical here which is √-288. We can make this i√288, and then further simplify by taking out 12 giving us 12i√2. Now we have
-24±12i√2/4
From here we just divide all the terms in the numerator by 4 and get -6±3i√2
I dont understand the question in english please xx
Answer:

Step-by-step explanation:



Answer: 12 sqrt(5)
Explanation:
First simplify:
= Sqrt(45)
= sqrt(9*5) sqrt of 9 is 3 so bring out 3
= 3sqrt(5)
= 2sqrt(20)
= 2sqrt(4*5) sqrt of 4 is 2 so bring that out and multiply it by 2
= 4sqrt(5)
= 5 sqrt(5) is already simplified
= 3sqrt(5) + 4 sqrt(5) + 5sqrt(5)
= 12 sqrt(5)
