how do I solve this?

Consider the following statement . Let A = (a , , az , as > be a vector and of be a scalar . If A = 0 , then either d= 0 or A = 0 i) cleartiexplain why the following proof is incorrect : Proof : If fr=0, then we are done. If A XO , then we have the following : of A = O Note that this is given d A = 0 A A =0 (i ) Provide the correct proof of the statement
