$t (k) = 60 + 115 e^{- 0.042 \cdot 20}$

Step 1

Multiply $- 0.042$ by $20$ .

$t (k) = 60 + 115 e^{- 0.84}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$t (k) = 60 + 115 (\frac{1}{e^{0.84}})$

Step 3

Combine $115$ and $\frac{1}{e^{0.84}}$ .

$t (k) = 60 + \frac{115}{e^{0.84}}$
