Question

# If A =, B =, C =, then which of the following statement is true-

- AB = BA
- AB = – BA
- A
^{2 }= BC
- A
^{2 }= B + C

^{2 }= BC^{2 }= B + C## The correct answer is: AB = – BA

### To find the correct statement in the given options.

Given, A =, B =, C =.

AB = x =

BA = x = = -AB

Therefore, AB = - BA.
