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

To simplify the expression 12(6^(5^(-4^))) + 7, you correctly started by replacing the exponent 6^ with its value, which is 36. So the expression becomes:

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

Next, you correctly simplified the negative exponent 5^-4^ by flipping the fraction to eliminate the negative exponent. The reciprocal of 5^-4^ is 1/(5^4^), which means that the expression now looks like this:

12(36/(1/(5^4^))) + 7

Simplifying further, you correctly calculated 5^4^, which is equal to 625. So the expression becomes:

12(36/(1/625)) + 7

To simplify the term 36/(1/625), you need to divide 36 by the reciprocal of 1/625, which is just 625. So:

36 / (1/625) = 36 * 625 = 22500

Now the expression looks like this:

12(22500) + 7

Finally, you correctly multiplied 12 by 22500, which equals 270000. Adding the 7, the final answer is:

270000 + 7 = 270007
