Whatever happened to just normal 70 times 6,000? The product is 420,000. If that was your question.

Answer:


70* 6000=420000

Explanation:

Given : Expression 'Product of 70 times 6000'.

To find : Calculate the product using associative and commutative properties?

Solution :

Associative property of multiplication,


a\cdot (b\cdot c)=(a\cdot b)\cdot c

Commutative property of multiplication,


a\cdot b=b\cdot a

Now, We solve the expression using properties


70* 6000=(7* 10)* (6* 1000)


70* 6000=7* 10* 6* 1000

Applying Commutative property,


70* 6000=7* 6* 10* 1000

Applying Associative property,


70* 6000=42* (10* 1000)


70* 6000=42* 10000


70* 6000=420000
