Question

which of the following does not show the commutative property of the addition a+b=b+a. 3+x=x+3. ab=ba. 3x+4y=4y+3x​

Answer 1

Answer:

Correct answer is : ab = ba

Answer 2

Answer:

C] ab = ba

Explanation:

Commutative property of addition states that:

→ a + b = b + a

for 2 numbers ‘a’ and ‘b’.

So option [A] shows commutative property.

Option B:

When ‘a’ and ‘b’ are 3 and x respectively,

3 + x = 3 + x

So, option [B] shows commutative property.

Option C:

Option C doesn't show commutative property of addition because there is no addition sign in between them.

Option D:

When ‘a’ and ‘b’ are 3x and 4y respectively,

3x + 4y = 4y + 3x

So, option [D] also shows commutative property.
