If 27\(^{x + 2}\) \(\div\) 9\(^{x + 1}\) = 3\(^{2x}\), find x. A. 3 B. 4 C. 5 D. 6
Show Content
Detailed Solution\(27^{x + 2} \div 9^{x + 1} = 3^{2x}\)\(3^{3(x + 2)} \div 3^{2(x + 1)} = 3^{2x}\) \(3^{3x + 6} \div 3^{2x + 2} = 3^{2x}\) \(\therefore (3x + 6) - (2x + 2) = 2x\) \(x + 4 = 2x \implies x = 4\) There is an explanation video available below. |
