Question

Pls pls, pls help me with my math

Answer 1

Answer:

C -> 94

Step-by-step 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 2

Answer:

C. 94

Step-by-step 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.
