Answer:
d. Associative Property of Multiplication
Explanation:
Given the expression:
[tex]\mleft(23\times24\mright)\times20=23\times(24\times20)[/tex]a,b, and c in R is said to satisfy the Associative Property of Multiplication if:
[tex]\mleft(a\times b\mright)\times c=a\times(b\times c)[/tex]Thus, the property being applied above is the Associative Property of Multiplication.
The correct choice is D.
