<span>Checking the existence conditions for the multiplication of matrices, the following properties are valid:
1- associative: </span>
<span>
2- distributive in relation to addition: </span>
<span>
3- neutral element: </span>
, where
is the identity matrix of order
p.s:.
For the multiplication of matrices is not worth the commutative property.
Therefore:
Answer <span>B) It satisfies the associative and distributive properties, but not the commutative property.</span>

DETAILED EXPLANATION
Look at .
Remove extraneous '1' from product highlight_red%28+1+%29
It becomes T%2Ahef%2Aor%2Amu%2Alar=A%5EP-g%2Aiv%2Aest%2Ahei%2Ant%2Aer%2Aes%2Atr%2Aat%2Aer.
Look at .
Reduce similar several occurrences of highlight_red%28+er+%29 to highlight_green%28+er%5E2+%29
It becomes .
Look at .
Moved these terms to the left highlight_green%28+-A%5EP+%29,highlight_green%28+g%2Aiv%2Aest%2Ahei%2Ant%2Aer%5E2%2Aes%2Atr%2Aat+%29
It becomes .
Result: T%2Ahef%2Aor%2Amu%2Alar-A%5EP%2Bg%2Aiv%2Aest%2Ahei%2Ant%2Aer%5E2%2Aes%2Atr%2Aat=0
