Answer:

C -> 94

Explanation:

1. FOLLOW PEMDAS

First, parentheses:

Solve
(4^(2) +1)


4^(2) is also 4·4=16

16+1 = 17

Solve
[3(4^(2) +1)] ->
[3(17)]

3·17 = 51

Solved so far:


2(51)-2^(3)

Second, exponents:


2^(3) -> 2·2·2 = 8

Solved so far:


2(51)-8

Third, multiplication:

2(51) -> 102

Solved so far:


102-8

Lastly, subtraction:

102-8 = 94

Answer:

C. 94

Explanation:

Take in account for PEMDAS: Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.

First is to find the answer within the innermost parenthesis:

(4²+1).

Find the exponent of 4², which is 16, leaving you the equation of

16+1, which equals to 17.

Next you multiply 3 by 17 (since the parenthesis of 17 borders 3):

17×3=51.

Next, multiply 51 by 2 (same rule as 3×17).

51×2=102.

After this you get 102-2³. Now, find 2³=2×2×2=8

This gets you to 102-8, ending up with your answer of 94.
