3^x+5=3^x+3+8/3 হলে x=?

Explanation:

Another Explanation (5): bài toán: 3^x+5=3^x+3+8/3 হলে x=?🤔 দেওয়া আছে, \(3^{x+5} = 3^{x+3} + \frac{8}{3}\) আমরা লিখতে পারি, \(3^{x+3+2} = 3^{x+3} + \frac{8}{3}\) \(3^{x+3} \cdot 3^2 = 3^{x+3} + \frac{8}{3}\) ধরি, \(3^{x+3} = a\) তাহলে, \(9a = a + \frac{8}{3}\) \(9a - a = \frac{8}{3}\) \(8a = \frac{8}{3}\) \(a = \frac{1}{3}\) এখন, \(3^{x+3} = \frac{1}{3}\) \(3^{x+3} = 3^{-1}\) সুতরাং, \(x+3 = -1\) \(x = -1 - 3\) \(x = -4\) উত্তর: -4 🎉
