[tex] {25}^{ \times - 2 } = {5}^{3 \times + 1} \times = [/tex]
[tex] {25}^{ \times - 2 } = {5}^{3 \times + 1} \times = [/tex]
[tex] \boxed{\begin{aligned}\sf {25}^{x - 2} &=\sf {5}^{3x + 1} \\ \sf { {(5}^{2}) }^{x - 2} &=\sf {5}^{3x + 1} \\ \sf {5}^{2x - 4} &= \sf {5}^{3x + 1} \\ \sf 2x - 4&=\sf 3x + 1\\ \sf 2x - 3x&=\sf1 + 4\\ \sf - x&=\sf 5\\ \sf x&=\sf - 5\end{aligned}}[/tex]
Jadi, nilai x adalah –5.
