Step-by-step explanation:
Find the common denominator for both unlike fractions.
EX: 1 2
12 8
The lowest common factor is both fractions is 24. Multiply both denominators to get 24.

You do not have to multiply each side by the same number.
This is just stuff you have to memorize, I can’t really explain much further than product always means multiplication. The “product of” means k*m
Answer:
-6
-6i
6i
6
Step-by-step explanation:
1) √4 . √-3 . √-3


-6
2) √-4 . √-3 . √-3
.
Therefore,
- 6i
3) √4 . √3 . √-3


6i
4) √4 . √3 . √3


Therefore, √4 . √3 . √3 = 2 . 3 = 6
