how can you call that final mess "simplified"?
I suspect the question has been mangled, since
(5/2)^2π₯-1 / (5/2)^2π₯ = 5^-1 = 1/5
so the whole thing is just
5^2π₯+1 + 1/5
I doubt this was the original intent

To simplify the given expression:
5^2π₯+1 + 2.5^2π₯-1 / 2.5^2π₯
First, we can rewrite 2.5 as 5/2:
5^2π₯+1 + (5/2)^2π₯-1 / (5/2)^2π₯
Now we can use the properties of exponents to simplify:
(5^(2π₯) * 5^1 + 5^(2π₯) * (5/2)^(-1)) / (5/2)^(2π₯)
(5^(2π₯+1) + 5^(2π₯) * (2/5)^(1)) / (5/2)^(2π₯)
(5^(2π₯+1) + 5^(2π₯) * 2/(5^2)) / (5/2)^(2π₯)
(5^(2π₯+1) + 5^(2π₯) * 2/25) / (5/2)^(2π₯)
Now we can simplify further if needed, but this is the fully simplified form of the expression.

Now we can simplify further if needed, but this is the fully simplified form of the expression.

Apologies for the confusion in my previous response. Let me simplify the expression correctly.
Given expression:
(5^2π₯+1 + 2.5^2π₯-1) / 2.5^2π₯
Rewriting the expression with 2.5 as 5/2:
(5^(2π₯+1) + (5/2)^(2π₯-1)) / (5/2)^(2π₯)
Using the property of exponents, we get:
(5^(2π₯) * 5^1 + (5/2)^(2π₯) / (5/2)^(2π₯)
(5^(2π₯) * 5 + (5/2)^(2π₯) / (5/2)^(2π₯)
(25 * 5^2π₯ + (5/2)^(2π₯) / (5/2)^(2π₯)
(25 * 5^2π₯ + 2^(2π₯) * 5^(-2π₯))
(25 * 5^(2π₯) + 1) / 5
25 * 5^(2π₯) / 5 + 1 / 5
5^(2π₯) * 5 + 1 / 5
25 * 5 + 1 / 5
125 + 1 / 5
126 / 5
So, the simplified expression is 126/5. Thank you for catching the error and helping with the correction.
