Simplify

12(6^/(5^-4^) + 7

My thoughts

12(36/(5^-4^) + 7

12(36/9) + 7

12 (4) + 7

12 * 11

132

Your notation is weird.

5^-4 = 1/5^4 = 1/625

No idea what 5^-4^ means, or 6^/...
^ means squared and is the way we have been taught to show it.

So the 1st part of your question reads

5 squared - 4 squared

2nd part is

6 squared divided by
