Answer 1

Answer:

$(1) \: \: \: \: {9}^{x - 8} \times {27}^{ - 2} = {9}^{ - x} \\ \\ {9}^{x - 8} \times {9}^{ - 6} = {9}^{ - x} \\ \\ {9}^{x - 14} = {9}^{ - x} \\ \\ compare = > \\ \\ x - 14 = - x \\ \\ 2x = 14 \\ \\ x = 7 \\ \\ (2) \: \: \frac{1.2}{2.3} = { (\frac{12}{23} )}^{3} = \frac{12 \times 12 \times 12}{23 \times 23 \times 23} = \frac{1728}{12167} \\ \\ (3) \: \: \: x + ( - \frac{9}{13} )( - 26) = \frac{8}{9} \\ \\ x + 18 = \frac{8}{9} \\ \\ x = \frac{8}{9} - 18 = \frac{8 - 9 \times 18}{9} = - \frac{154}{9} \\ \\ (4) \: (2x) \times (6y) \times ( - \frac{5}{7} x \times \frac{7}{8} y) = - \frac{15}{2} {x}^{2} {y}^{2} \\ \\ (5)2m = 11 \\ \\ m = \frac{11}{2} \\ \\ (6) \: (i)9x = \frac{2}{5} \\ \\ x = \frac{2}{45} \\ \\ (ii) \: - \frac{7}{8} x = - \frac{7}{2} \\ \\ x = 4$
