√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
