52x - 3 - 2 × 52 = 52 × 3

52x - 3 - 2 × 52 = 52 × 3 Ta có : \(5^{2x-3}-2.25\) = \(25.3\) => \(5^{2x-3}=75+50\) => \(5^{2x-3}=125\) => \(5^{2x}:5^3=125\) => \(5^{2x}=15625\) Ta lại có: \(5^6=15625\) => \(5^6=5^{2x}=5^{2.3}\) Vậy x = 3Câu trả lời: 52x - 3 - 2 × 52 = 52 × 3 Ta có : \(5^{2x-3}-2.25\) = \(25.3\) => \(5^{2x-3}=75+50\) => \(5^{2x-3}=125\) => \(5^{2x}:5^3=125\) => \(5^{2x}=15625\) Ta lại có: \(5^6=15625\) => \(5^6=5^{2x}=5^{2.3}\) Vậy x = 3
