Answer 2

√16 = 4
3(4) = 12
---------------------------------------------
-2³ = -2(-2)(-2)

-2(-2) = 4
4(-2) = -8
--------------------------------------------
4(5 - 2²)

follow PEMDAS, first do the square

2² = 4

Next, do the subtraction

5 - 4 = 1

Finally, multiply

4(1) = 4

Combine all the terms together. Remember to bring down signs.

12 - (-8) + 4

12 - (-8) = 12 + 8 = 20

20 + 4 = 24

24 is your answer

hope this helps
