Answer:
The correct option is 4. The given equation illustrates the Associative Property of Addition.
Step-by-step explanation:
Te given equation is
[tex]9+(8+1)=(9+8)+1[/tex]
According to the Associative Property of Addition then order of addition does not affect the resultant, if a,b,c are three numbers then a+(b+c) and (a+b)+c are equivalent expression.
[tex]a+(b+c)=(a+b)+c[/tex]
The given equation illustrates the Associative Property of Addition.
Therefore the correct option is 4.
