Answer:
separate and square both the top and bottom
the square of square root three is just 3 and the square of 3 (the bottom of the fraction) is 9
so now you have 3(i^2) /9
you can simplify this by three and then i^2 is -1
you now have -1/3 and thats the final answer
Answer:
6/10
9/15
12/20
Step-by-step explanation:

12 for the first one, 6*4=24 24 divided by 2
