Question

3^x+2 + 3^x+1 = 4/3 solve​

Answer 1

`{3}^(x + 2) + 3 ^(x + 1) = (4)/(3) \\ = > {3}^(x) * {3}^(2) + {3}^(x) * 3 = (4)/(3) \\ = > {3}^(x) * 9 + {3}^(x) * 3 = (4)/(3) \\ = > {3}^(x) (9 + 3) = (4)/(3) \\ = > {3}^(x) * 12 = (4)/(3) \\ = > {3}^(x) = (4)/(3) * (1)/(12) \\ = > {3}^(x) = (1)/(3 * 3) \\ = > {3}^(x) = {3}^( - 2) \\ = > x = - 2`
