Find x and y

Find \(x\) and \(y\), if \(5^{3x} = 125\) and \(10^y = 0.001\)

Solution

\[ 5^{3x} = 125 \]

\[ \Rightarrow 5^{3x} = 5^3 \]

\[ \Rightarrow 3x = 3 \]

\[ \Rightarrow x = 1 \]

\[ 10^y = 0.001 \]

\[ \Rightarrow 10^y = 10^{-3} \]

\[ \Rightarrow y = -3 \]

Final Answer:

\[ \boxed{x = 1,\; y = -3} \]
