Answer:
1.![5+6=6+5](https://tex.z-dn.net/?f=5%2B6%3D6%2B5)
Step-by-step 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](https://tex.z-dn.net/?f=a%2Bb%3Db%2Ba)
1.![5+6=6+5](https://tex.z-dn.net/?f=5%2B6%3D6%2B5)
![5+6=11](https://tex.z-dn.net/?f=5%2B6%3D11)
![6+5=11](https://tex.z-dn.net/?f=6%2B5%3D11)
Hence,
.
Therefore, it is an example of commutative property.
![2.2+(4+6)=(2+4)+6](https://tex.z-dn.net/?f=2.2%2B%284%2B6%29%3D%282%2B4%29%2B6)
Associative property of addition : ![a+(b+c)=(a+b)+c](https://tex.z-dn.net/?f=a%2B%28b%2Bc%29%3D%28a%2Bb%29%2Bc)
Hence, it represents the associative property of addition not commutative property of addition.
3.![3\times 8=8\times 3](https://tex.z-dn.net/?f=3%5Ctimes%208%3D8%5Ctimes%203%20)
It represents the commutative property of multiplication.
Associative property of multiplication:![a\times b=b\times a](https://tex.z-dn.net/?f=a%5Ctimes%20b%3Db%5Ctimes%20a)
4.10+3=7+6
It does not satisfied the commutative property of addition.
Hence, option 1 is true.
