Answer:
addition
Step-by-step explanation:
The given expression is [tex](8-2x)^2+4[/tex]
We want to determine the last operation performed when evaluating this expression for x=3.
We substitute to get:
[tex](8-2*3)^2+4[/tex]
Multiply within the parenthesis to get:
[tex](8-6)^2+4[/tex]
Subtract to get:
[tex]2^2+4[/tex]
Evaluate the exponent to get:
4+4
Add to obtain:
8
Hence the final operation is addition
