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

Answer:
7:12
Step-by-step explanation:
21 and 36 are both multiples of 3.
3 times 7 is 21, and 3 times 12 is 36.
Now, this ratio becomes: 3 x 7 : 3 x 12
Dividing by 3 on both sides,, we have: 7:12. The ratio 7:12 can't be simplified further, so that's the answer.
