Question

Resolva
a)9x+¹ - ²√3

Answer 1

${9}^{x + 1} = \sqrt[3]{3} \\ ( { {3}^{2} })^{x + 1} = {3}^{ \frac{1}{3} } \\ {3}^{2x + 2} = {3}^{ \frac{1}{3} } = \\ 2x + 2 = \frac{1}{3} = \\ 2x = \frac{1}{3} - 2 \\ 2x = \frac{1 - 6}{3} \\ 2x = - \frac{5}{3} \\ x = - \frac{5}{3} \times 2 \\ x = - \frac{10}{3}$
