5^3x/5^-4×25/5x=5^20/5^12​

Answer 1

Answer:

hey mate

here is your answer

\begin{lgathered}\frac{ {5}^{3x} }{ {5}^{ - 4} } \times \frac{25}{ {5}^{4} } = \frac{ {5}^{20} }{ {5}^{1 2} } \\ {5}^{3x + 4} \times {5}^{2 - 4} = {5}^{20 - 12} \\ {5}^{3x + 4 + 2 - 4} = {5}^{8} \\ {5}^{3x + 2 } = {5}^{8} \\ 3x + 2 = 8 \\ 3x = 8 - 2 \\ 3x = 6 \\ x = 2\end{lgathered}
