Answer:
177
Step-by-step explanation:
PEMDAS
The PEMDAS rule is an acronym representing the order of operations in math:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Given expression:
[tex](3-4^2)^2+8[/tex]
Parentheses
Begin by calculating the part inside the parentheses.
Following PEMDAS, calculate the exponent first:
[tex]\implies (3-4^2)^2+8=(3-16)^2+8[/tex]
Then carry out the subtraction:
[tex]\implies (3-16)^2+8=(-13)^2+8[/tex]
Exponents
[tex]\textsf{Apply the exponent rule}: \quad (-a)^n=a^n, \quad \textsf{if }n \textsf{ is even}[/tex]
[tex]\implies (-13)^2+8=169+8[/tex]
Addition
[tex]\implies 169+8=177[/tex]
Therefore:
[tex]\implies (3-4^2)^2+8=177[/tex]
