Lets multiply using commutative law and associative law

We must understand that,

Commutative law, in mathematics, either of two laws relating to number operations of addition and multiplication, stated symbolically: a + b = b + a and ab = ba.

Associative law, in mathematics, either of two laws relating to number operations of addition and multiplication, stated symbolically: (a + b) + c = a + (b + c), and a(bc) = (ab)c.

We have,

We can write as,

According to the commutative law of multiplication,

So,

Also, by associative law of multiplication,

We can solve it by any way.

So,

Thus, the answer is .
