Question

Which equation exemplifies the commutative property of addition???

1: 5+6=6+5

2: 2+(4+6) = (2+4) +6

3: 3x8=8x3

4: 10+3=7+6

Answer 1

Commutative property is "a + b = b + a"

Therefore your answer is 1. 5 + 6 = 6 + 5

Answer 2

Answer:

1.
`5+6=6+5`

Explanation:

We have to find the equation which represents the commutative property of addition.

Commutative property of addition:Let a and b are two integers satisfied the commutative property of addition , then

`a+b=b+a`

1.
`5+6=6+5`

`5+6=11`

`6+5=11`

Hence,
`5+6=6+5`.

Therefore, it is an example of commutative property.

`2.2+(4+6)=(2+4)+6`

Associative property of addition :
`a+(b+c)=(a+b)+c`

Hence, it represents the associative property of addition not commutative property of addition.

3.
`3* 8=8* 3`

It represents the commutative property of multiplication.

Associative property of multiplication:
`a* b=b* a`

4.10+3=7+6

It does not satisfied the commutative property of addition.

Hence, option 1 is true.
