Question

5x70=5x( X10)
5x70=(5x )x10
5x70= X10=

Find the product using properties of multiplication.

Answer 1

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).
