The OCR did not extract the equations correctly. I'll proceed by solving each equation manually based on the visual content from the uploaded image.

### Given problems:
1. \( 64 = 8^{x - 2} \)
2. \( 3^{2x} = 81 \)
3. \( 16^{-x} = \frac{1}{64} \)
4. \( 3^{4x} = 9^{x + 1} \)
5. \( 4^{x + 1} = 64 \)

Let's solve each one step-by-step.

### 1) \( 64 = 8^{x - 2} \)
Express 64 and 8 as powers of 2:
\[
64 = 2^6 \quad \text{and} \quad 8 = 2^3
\]
Thus, the equation becomes:
\[
2^6 = (2^3)^{x - 2} \implies 2^6 = 2^{3(x - 2)}
\]
Equating exponents:
\[
6 = 3(x - 2) \implies 6 = 3x - 6 \implies 3x = 12 \implies x = 4
\]

### 2) \( 3^{2x} = 81 \)
Express 81 as a power of 3:
\[
81 = 3^4
\]
So,
\[
3^{2x} = 3^4 \implies 2x = 4 \implies x = 2
\]

### 3) \( 16^{-x} = \frac{1}{64} \)
Express 16 and 64 as powers of 2:
\[
16 = 2^4 \quad \text{and} \quad 64 = 2^6
\]
Therefore,
\[
(2^4)^{-x} = \frac{1}{2^6} \implies 2^{-4x} = 2^{-6}
\]
Equating exponents:
\[
-4x = -6 \implies x = \frac{3}{2}
\]

### 4) \( 3^{4x} = 9^{x + 1} \)
Express 9 as a power of 3:
\[
9 = 3^2
\]
Thus, the equation becomes:
\[
3^{4x} = (3^2)^{x + 1} \implies 3^{4x} = 3^{2(x + 1)}
\]
Equating exponents:
\[
4x = 2(x + 1) \implies 4x = 2x + 2 \implies 2x = 2 \implies x = 1
\]

### 5) \( 4^{x + 1} = 64 \)
Express 4 and 64 as powers of 2:
\[
4 = 2^2 \quad \text{and} \quad 64 = 2^6
\]
The equation becomes:
\[
(2^2)^{x + 1} = 2^6 \implies 2^{2(x + 1)} = 2^6
\]
Equating exponents:
\[
2(x + 1) = 6 \implies 2x + 2 = 6 \implies 2x = 4 \implies x = 2
\]

### Final Answers
1. \( x = 4 \)
2. \( x = 2 \)
3. \( x = \frac{3}{2} \)
4. \( x = 1 \)
5. \( x = 2 \)
