Answer 1

\(\frac{3^8.20^5}{6^8.10^2}=\frac{3^8.2^{10}.5^5}{2^8.3^8.2^2.5^2}=5^3=125\)

Answer 2

\(\frac{3^8.20^8}{6^8.10^{10}}=\frac{3^8.\left(5.2^2\right)^5}{\left(3.2\right)^8.\left(2.5\right)^{10}}\)=\(\frac{3^8.5^5.2^{10}}{3^8.2^8.2^{10}.5^{10}}=\frac{1}{2^8.5^5}\)= \(\frac{1}{800000}\)

Answer 3

\(\frac{3^8.20^5}{6^8.10^2}=\frac{3^8.\left(2.10\right)^5}{\left(2.3\right)^8.10^2}=\frac{3^8.2^5.10^5}{2^8.3^8.10^2}=\frac{10^3}{2^3}=\frac{1000}{8}=125\)
