Answer 1

Answer: 177

Step-by-step explanation:

1. 4x4=16

(3-16)^2+8

2. 3-16=-13

(-13)^2+8

3. -13x-13=169

169+8

4.169+8=177

177

Answer 2

Answer:

177

Step-by-step explanation:

                       

PEMDAS

The PEMDAS rule is an acronym representing the order of operations in math:

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Given expression:

$(3-4^2)^2+8$

Parentheses

Begin by calculating the part inside the parentheses.

Following PEMDAS, calculate the exponent first:

$\implies (3-4^2)^2+8=(3-16)^2+8$

Then carry out the subtraction:

$\implies (3-16)^2+8=(-13)^2+8$

Exponents

$\textsf{Apply the exponent rule}: \quad (-a)^n=a^n, \quad \textsf{if }n \textsf{ is even}$

$\implies (-13)^2+8=169+8$

Addition

$\implies 169+8=177$

Therefore:

$\implies (3-4^2)^2+8=177$
