Answer:
1. Correct
2. Correct again
3. 4
Step-by-step explanation:
The first one is correct If you need an explanation let me know.
Second one is the same
For the third one since 4-2 is in () you would have to do it first
4-2= 2
Then you will have to do it to the 2nd power which would mean...
2 x 2= 4
So 4 would be your answer.
Hope this helps :)
