Step-by-step Solution
Solve the equation \( 3^{x} \cdot 4^{x-1}=\frac{1}{4} \cdot 144^{2-x} \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(3^{x}\times 4^{x-1}=\frac{1}{4}\times 144^{2-x}\)
- step1: Rewrite the expression:
\(12^{x}=144^{2-x}\)
- step2: Rewrite the expression:
\(12^{x}=12^{4-2x}\)
- step3: Set the exponents equal:
\(x=4-2x\)
- step4: Move the variable to the left side:
\(x+2x=4\)
- step5: Add the terms:
\(3x=4\)
- step6: Divide both sides:
\(\frac{3x}{3}=\frac{4}{3}\)
- step7: Divide the numbers:
\(x=\frac{4}{3}\)
The solution to the equation \(3^{x} \cdot 4^{x-1}=\frac{1}{4} \cdot 144^{2-x}\) is \(x=\frac{4}{3}\) or \(x=1.\dot{3}\).
