To solve the expression , let’s break it down a bit. The notation is a bit unconventional, but if we interpret it as , then the expression becomes since . This means you first multiply 10000 by 81, which gives you 810000. Now, you’ll divide that by , leaving you with .

Now, let’s say is any positive number; plugging in different values for will give you various results, which is essentially how algebra works! Just remember that if you set to 0, you’ll run into division-by-zero issues, so be careful with that!
