Explanation:

Step1: Evaluate $e^{- 0.2}$

Use the exponential - function property. The value of the exponential function $y = e^{x}$ can be calculated using a calculator. When $x=-0.2$, we have $e^{-0.2}=\frac{1}{e^{0.2}}$. Using a calculator, $e^{-0.2}\approx0.81873$. Rounding to the nearest thousandth, $e^{-0.2}\approx0.819$.

Step2: Evaluate $245e^{0.15}$

First, find the value of $e^{0.15}$ using a calculator. $e^{0.15}\approx1.161834$. Then multiply by 245: $245\times e^{0.15}=245\times1.161834 = 284.64933$. Rounding to the nearest thousandth, $245e^{0.15}\approx284.649$.

Answer:

$e^{-0.2}\approx0.819$ $245e^{0.15}\approx284.649$
