We are given the expression:

$\frac{8 - 4^{2n+1} \times (4^n)^7}{32^{n+1}}$

Step 1: Simplify the powers

Let's break this down into parts and simplify:

1. Simplify $4^{2n+1}$: Recall that $4 = 2^2$, so: $4^{2n+1} = (2^2)^{2n+1} = 2^{2(2n+1)} = 2^{4n+2}$

2. Simplify $(4^n)^7$: Again, since $4 = 2^2$: $(4^n)^7 = (2^{2n})^7 = 2^{14n}$

3. Simplify $32^{n+1}$: Recall that $32 = 2^5$, so: $32^{n+1} = (2^5)^{n+1} = 2^{5(n+1)} = 2^{5n+5}$

Step 2: Substitute these simplified powers back into the expression

Now, we substitute these values into the original expression:

$\frac{8 - 2^{4n+2} \times 2^{14n}}{2^{5n+5}}$

Step 3: Simplify the numerator

We have $2^{4n+2} \times 2^{14n}$. By the laws of exponents: $2^{4n+2} \times 2^{14n} = 2^{(4n+2+14n)} = 2^{18n+2}$

Thus, the expression becomes:

$\frac{8 - 2^{18n+2}}{2^{5n+5}}$

Step 4: Simplify the constant 8

Since $8 = 2^3$, we can rewrite the expression as:

$\frac{2^3 - 2^{18n+2}}{2^{5n+5}}$

Step 5: Simplify the final expression

Now we separate the two terms in the numerator:

$\frac{2^3}{2^{5n+5}} - \frac{2^{18n+2}}{2^{5n+5}}$

Each of these can be simplified using the properties of exponents:

1. $\frac{2^3}{2^{5n+5}} = 2^{3 - (5n+5)} = 2^{3 - 5n - 5} = 2^{-5n - 2}$
2. $\frac{2^{18n+2}}{2^{5n+5}} = 2^{(18n+2) - (5n+5)} = 2^{18n + 2 - 5n - 5} = 2^{13n - 3}$

Final simplified expression:

$2^{-5n-2} - 2^{13n-3}$

This is the simplified form of the given expression.
