Question

Please solve q.1 a) step by step

Answer 1

Step-by-step explanation:

${( \frac{16}{25}})^{1 - 2x} = {( \frac{125}{64}})^{x - 2} \\ {( \frac{25}{16}})^{2x - 1} = {( \frac{125}{64} })^{x - 2} \\ {( \frac{5}{4} })^{4x - 2} = {( \frac{5}{4} })^{3x - 6} \\ \\ base \: same \: then \: powers \: is \: also \: same \: \\ now \: \\ 4x - 2 = 3x - 6 \\ 4x - 3x = 2 - 6 \\ x = - 4answer$
