(C) \(5^{11.1}\)
(D)\(7^{9.1}\)
(E)\(11^{5.1}\)
\(2^{27.3} = 2^{2.73(10)}\)
\(2.73 ≈ 3\)
i.e. \(2^{3(10)} = 8^{10}\)
\(3^{18.2} = 3^{1.82(10)}\)
\(1.82 ≈ 2\)
i.e. \(3^{2(10)} = 9^{10}\)
\(5^{11.1} = 5^{1.11(10)}\)
\(1.11 ≈ 1\)
i.e. \(5^{1(10)} = 5^{10}\)
\(7^{9.1} = 7^{0.91(10)}\)
\(0.91 ≈ 1\)
i.e. \(7^{1(10)} = 7^{10}\)
\(11^{5.1} = 11^{0.51(10)}\)
\(0.51 ≈ 0.5\)
i.e. \(11^{0.5(10)} = \sqrt{11}^{10}\)
Hence, option B
