Answer 2

a) \(12^{10}:3^{10}=\left(12:3\right)^{10}=4^{10}\)

b) \(4^5.3^{10}=4^5.3^{2.5}=4^5.\left(3^2\right)^5=4^5.9^5=\left(4.9\right)^5=36^5\)

c) \(9^{10}:27^4=\left(3^2\right)^{10}:\left(3^3\right)^4=3^{2.10}:3^{3.4}=3^{20}:3^{12}=3^8\)

d) \(15^8:9^4=15^8:\left(3^2\right)^4=15^8:3^8=\left(15:3\right)^8=5^8\)

Answer 3

\(12^{10}:3^{10}=\left(12:3\right)^{10}=4^{10}\)

\(4^5:3^{10}=2^{10}:3^{10}=\frac{2}{3}^{10}\)

\(9^{10}:27^4=3^{20}:3^{12}=3^{20-12}=3^8\)

\(15^8:9^4=225^4:9^4=\left(225:9\right)^4=25^4\)
