Because of the commutative property of multiplication, it is true that

3/4

×

4

=

4

×

4/3

. However, these expressions can be calculated in different ways even though the solutions will be the same.

Below, show two different ways of solving this problem.

It is Commutative

Step-by-step explanation:

An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.

Given the operation ∆ defined by:

a∆b=a X b

a∆b=

=3

Similarly, for the right hand side.

Therefore:

b∆a=

=3

These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:

a∆b=b∆a=3

what level of math? also i don't need to be paid if i can you.
