Answer
$a) 3.1^{2.7}\approx 21.217 \\ b) 3.14^{2.71}\approx 22.217 \\c) 3.141^{2.718}\approx 22.440 \\d) \pi^{e}\approx 22.459$
Work Step by Step
Use a calculator to compute the given expression and then we round-off the answer to three decimal places.
$a) 3.1^{2.7}\approx 21.217 \\ b) 3.14^{2.71}\approx 22.217 \\c) 3.141^{2.718}\approx 22.440 \\d) \pi^{e}\approx 22.459$
