a) \(2^{300}=\left(2^3\right)^{100}=8^{100}\)
\(3^{200}=\left(3^2\right)^{100}=9^{100}>8^{100}\)
\(\Rightarrow2^{300}< 3^{200}\)
b) \(99^{20}=\left(99^2\right)^{10}=9801^{10}< 9999^{10}\Rightarrow99^{20}< 9999^{10}\)
c) \(3^{500}=\left(3^5\right)^{100}=243^{100}\)
\(7^{300}=\left(7^3\right)^{100}=343^{100}>243^{100}\)
\(\Rightarrow3^{500}< 7^{300}\)
\(\left(d\right):202^{303}=\left(202^3\right)^{101}=8242408^{101}>303^{202}=\left(303^2\right)^{101}=91809^{101}\)
\(\left(e\right):107^{50}=\left(107^2\right)^{25}=11449^{25}< 73^{75}=\left(73^3\right)^{25}=389017^{25}\)
d) \(202^{303}=\left(202^3\right)^{101}=\left(8.101^3\right)^{101}=\left(808.101^2\right)^{101}\)
\(303^{202}=\left(303^2\right)^{101}=\left(9.101^2\right)^{101}< \left(808.101^2\right)^{101}\)

e) \(107^{50}=\left(107^2\right)^{25}=11449^{25}\)
\(73^{75}=\left(73^3\right)^{25}=389017^{25}>11449^{25}\)
