The calculation 5(34)(20) = 5(20)(34) = 100(34) = 3400 uses the Commutative Property of Multiplication, which states that the multiplication of numbers remains the same regardless of their arrangement.
Based on the calculation provided: 5(34)(20) = 5(20)(34) = 100(34) = 3400, the property being used is Option 2: Commutative Property of Multiplication. This property states that the multiplication of two or more numbers remains the same regardless of the order in which the numbers are arranged. For instance, in the equation, the order of 34 and 20 is swapped, but the result remains the same, demonstrating the commutative property of multiplication.
