Is it $8^{x} +1 = 32\sqrt{2}$ or $8^{x+1} = 32\sqrt{2}$

3. how to perform the indicated operation reduce your answer if it is not simplified?

1.4x - 2x
4x-y 4x-y

2 2
2.x -y
x-y x-y

$8^{x+1} = 32 \sqrt{2} \Rightarrow (2^3)^{(x+1)} = 2^5 \, 2^{1/2} \Rightarrow 2^{3x + 3} = 2^{11/2} \Rightarrow 3x + 3 = \frac{11}{2}$.
