Solve 5^(x-2) × 3^(2x-3) = 135

Solve: \(5^{x-2} \times 3^{2x-3} = 135\)

Solution

\[ 5^{x-2} \times 3^{2x-3} = 135 \]

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

\[ \Rightarrow \frac{5^x}{5^2} \times \frac{3^{2x}}{3^3} = 5 \times 3^3 \]

\[ \Rightarrow \frac{5^x \cdot 3^{2x}}{5^2 \cdot 3^3} = 5 \cdot 3^3 \]

\[ \Rightarrow 5^x \cdot 3^{2x} = 5^3 \cdot 3^6 \]

\[ \Rightarrow (5 \cdot 3^2)^x = (5 \cdot 3^2)^3 \]

\[ \Rightarrow 45^x = 45^3 \]

\[ \Rightarrow x = 3 \]

Final Answer:

\[ \boxed{x = 3} \]
