Answer:
Option (-2-1)(8)=-2(1-8) is correct
The expression (-2-1)(8)=-2(1-8) represents the associative property of multiplication .
Explanation:
Given expression is (-2-1)(8)=-2(1-8)
Associative property of multiplication is given by
(a+b)c=a(b+c)
Comparing the equations (-2-1)(8)=-2(1-8) and (a+b)c=a(b+c) we get that the given expression is in the form of (a+b)c=a(b+c)
Therefore the given equation represents the associative property of multiplication .
Therefore option (-2-1)(8)=-2(1-8) is correct
The expression (-2-1)(8)=-2(1-8) represents the associative property of multiplication .
