Quizplus · Accepted Answer

1) First, we need to solve the expression inside the brackets:  
 4^2 = 16 and  √4 = 2

So, 4^2 + √4 = 16 + 2 = 18

2) Then, we multiply 18 by 3:

3[4^2 + √4] = 3(18) = 54

3) Next, we need to evaluate 40 ÷ 10:

40 ÷ 10 = 4

4) Finally, we subtract 4 from 54:

54 - 4 = 50

Therefore, the answer is D) 50.
