Solve 4^(x-1) × (0.5)^(3-2x) = (1/8)^x

Solve: \(4^{x-1} \times (0.5)^{3-2x} = \left(\frac{1}{8}\right)^x\)

Solution

\[ 4^{x-1} \times (0.5)^{3-2x} = \left(\frac{1}{8}\right)^x \]

\[ \Rightarrow (2^2)^{x-1} \times (2^{-1})^{3-2x} = (2^{-3})^x \]

\[ \Rightarrow 2^{2x-2} \times 2^{-3+2x} = 2^{-3x} \]

\[ \Rightarrow 2^{2x-2-3+2x} = 2^{-3x} \]

\[ \Rightarrow 2^{4x-5} = 2^{-3x} \]

\[ \Rightarrow 4x – 5 = -3x \]

\[ \Rightarrow 7x = 5 \]

\[ \Rightarrow x = \frac{5}{7} \]

Final Answer:

\[ \boxed{x = \frac{5}{7}} \]
