We are given expression: (3×2)×5.
We can see we have multiplication sign there.
Therefore, we can apply associative property of multiplication.
The associative property of multiplication is :
(a × b) × c = a × ( b × c).
We just need to regroup the multiplications.
On applying associative property of multiplication in (3×2)×5 , we get
3×(2×5).
Therefore, 3×(2×5) is the another way to group the factor (3×2)×5.
