Answer:
(A)(3×8)×6=3×(8×6)
Explanation:
Definition: A set S is said to be associative under the operation x if the following holds:
[tex]\begin{gathered} \forall a,b,c\in S \\ a\times(b\times c)=(a\times b)\times c \end{gathered}[/tex]Therefore, the number sentence that illustrates the associative property of multiplication is:
[tex]\mleft(3\times8\mright)\times6=3\times\mleft(8\times6\mright).[/tex]The correct choice is A.
