Hello, the topic you mentioned is the sixth question (liberal arts volume): If A and B are real numbers, then "0"

Answer: Sufficient conditions:

Because 0

Therefore, ab

Therefore, it is not a sufficient condition.

Necessary conditions:

B< 1/a can't infer 0.

So it is not a necessary condition.

So the final conclusion is that it is neither a sufficient condition nor a necessary condition.

I hope you will be satisfied with my answer. But when answering questions in the examination room, it is best to choose the simplest and fastest way to do it.
