Implied multiplication happens when we have variables and numbers written without any sign between them; also it happens when we write parentheses, in this case this will mean that:
![\begin{gathered} 3(bc)=2d \\ 3(b* c)=2* d \\ 3* b* c=2* d \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/z4r2mbfw95clze8j0qsqju1tcvfht5y59i.png)
Therefore, the equation written with the multiplication denoted explicitly is:
![3* b* c=2* d](https://img.qammunity.org/2023/formulas/mathematics/college/gyh3o15gdbfvso98qta485vft6i0qe7b9c.png)
