Answer 1

${3}^{2x - 1} \times {3}^{x - 2} \times {3}^{3x + 7} = 27 \\ {3}^{2x - 1 + x - 2 + 3x + 7} = {3}^{3} \\ {3}^{6x + 4} = {3}^{3} \\ 6x + 4 = 3 \\ 6x = 3 - 4 \\ 6x = - 1 \\ x = \frac{ - 1}{6}$

${5}^{2x - 3} \times {5}^{5x - 2} \times {5}^{3x + 5} = 625 \\ {5}^{2x - 3 + 5x - 2 + 3x + 5} = {5}^{4} \\ {5}^{10x} = {5}^{4} \\ 10x = 4 \\ x = \frac{4}{10} \\ x = \frac{2}{5}$
