It’s not unheard of to find, in an exercise, “Simplify 4x²/2x”. The answer is almost guaranteed to be 2x. (There are some interesting exceptions, but they’re not really important). More often such a question would use fraction notation, but not always, to prevent exercises taking up too much space.
What’s going on is that the multiplication of the 2 and x, because they are written without a symbol in between, is seen as morally being something you should do first.
And in such exercise contexts, it’s unlikely to be misunderstood. But it’d still be better to be clear about it.
