ANSWER:

Some FORMULAS To REMEMBER :-

  • \bf\color{red}{\frac{1}{a^1}=a^{-1}}

  • \bf\color{green}{a^x=a^y => x = y}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

= > 5 {}^{(2x - 1)} = \frac{1}{125 {}^{(x - 3)} } \\ = > {5}^{(2x - 1)} = \frac{1}{5 {}^{3(x - 3)} } \\ = > 5 {}^{(2x - 3)} = \frac{1}{ {5}^{(3x - 9)} } \\ = > {5}^{(2x - 3)} = {5}^ { - (3x - 9)} \\ = > {5}^{(2x - 3)} = {5}^{ - 3x + 9} \\ = > 2x - 3 = - 3x + 9 \\ = > 2x + 5x = 9 + 1 \\ = > 5x = 10 \\ = > x = \frac{10}{5} \\ = > \boxed{x = 2}
