Final answer:
The question examines if A equals B given certain equations involving A, B, and F. It's concluded that one cannot determine A equals B without further information or specific conditions being met, such as the non-zero nature of F.
Step-by-step explanation:
The question is asking to analyze different equations to determine if they imply that A equals B under certain conditions.
(a) If A × F = B × F, it's not necessarily true that A = B because F could be zero, making both sides of the equation zero regardless of A and B.(b) If A FB F, this appears to be a typo or an incomplete expression. Therefore, we cannot conclude anything about the relationship between A and B without further information or context.(c) If FÃ = BF, there is not enough information to conclude that A = B. The variable F could be a matrix with certain properties that do not allow us to cancel it from both sides or it could be a non-invertible element. Additional context or clarification is necessary.
