Chapter 5 - Exponential and Logarithmic Functions - 5.3 Exponential Functions - 5.3 Assess Your Understanding: 16

a)$\approx6.498$ b)$\approx6.543$ c)$\approx6.580$ d)$\approx6.581$

We calculate them by using a calculator and then round them to the first $3$ decimal digits. a)$2^{2.7}\approx6.498$ b)$2^{2.71}\approx6.543$ c)$2^{2.718}\approx6.580$ d)$2^{e}\approx6.581$
