Does implicit multiplication have higher priority than regular multiplication?

There is no universal rule that always makes implicit multiplication higher priority in every context. In many textbooks, an expression like $$2x$$ feels tightly grouped because it represents one coefficient times a variable. But when mixed with division symbols, ambiguity can appear: $$a/bc.$$ Some readers interpret this as $$\frac{a}{bc},$$ while others read it left to right as $$\left(\frac{a}{b}\right)c.$$ That is why serious mathematical writing avoids this form when the meaning matters. Use parentheses or a fraction bar. So the best answer is: implicit multiplication can be treated as visually tighter by convention in some settings, but you should not rely on that convention for ambiguous expressions.
