5x70=5x( X10)
5x70=(5x )x10
5x70= X10=
Find the product using properties of multiplication.
By the associative property of multiplication, we can reorder the factors:
5x70 = (5x7)x10
By the commutative property of multiplication, we can rearrange the factors:
(5x7)x10 = 7x5x10
By the commutative property of multiplication again, we can rearrange the factors:
7x5x10 = 5x7x10
By the associative property of multiplication again, we can reorder the factors:
5x7x10 = 5x(7x10)
Therefore, 5x70 = 5x(7x10).
