\(\left(\frac{3}{5}\right)^{2012}:\left(\frac{9}{25}\right)^{1000}=\left(\frac{3}{5}\right)^{2012}:\left(\frac{3}{5}\right)^{2000}=\left(\frac{3}{5}\right)^{12}\)
\(\left(\frac{3}{5}\right)^{2003}:\left(\frac{9}{25}\right)^{1000}\)
\(=\left(\frac{3}{5}\right)^{2003}:\left(\left(\frac{3}{5}\right)^2\right)^{1000}\)
\(=\left(\frac{3}{5}\right)^{2003}:\left(\frac{3}{5}\right)^{2000}\)
\(=\left(\frac{3}{5}\right)^3\)
\(=\frac{27}{125}\)
\(\left(\frac{3}{5}\right)^{2003}:\left(\frac{9}{25}\right)^{1000}\)
\(=\frac{3}{5}.\left[\left(\frac{3}{5}\right)^2\right]^{1000}:\left(\frac{9}{25}\right)^{1000}\)
\(=\frac{3}{5}.\left(\frac{9}{25}\right)^{1000}:\left(\frac{9}{25}\right)^{1000}\)
\(=\frac{3}{5}\)
=(3/5)2012:(3/5)2000=3/512
\(\left(\frac{3}{5}\right)^{2012}:\left(\frac{9}{25}\right)^{1000}\)
\(=\left(\frac{3}{5}\right)^{2012}:\left[\left(\frac{3}{5}\right)^2\right]^{1000}\)
\(=\left(\frac{3}{5}\right)^{2012}:\left(\frac{3}{5}\right)^{2000}\)
\(=\left(\frac{3}{5}\right)^{12}\)
