Answer:
Associative property of Multiplication.
Explanation:
The Associative property of multiplication states that if a, b and c are any real number then we can group the number in any combination during multiplication, the results would always be same i.e.,
a × (b × c) = (a × b) × c
Therefore in given expression 5 × 7 × 4 = 5 × 4 × 7
Therefore in the above expression associative property of multiplication is demonstrated.
