The logarithm of a product is equal to the sum of logarithms:

$\ln(3^{-e}e^3)=\ln3^{-e}+\ln e^3$

Drop the exponents:

$-e\ln3+3\ln e$

The logarithm of a number is equal to 1 if the base of the logarithm is the same as the number itself:

$-e\ln3+3$

Answer:

Step-by-step explanation:

a) Use t=10 in the given formula and do the arithmetic.

39.07×1.021^10 ≈ 48.0951 ≈ 48.10 . . . millions

b) The derivative of p(t) is ...

p'(t) = p(t)·ln(1.021) ≈ 0.8120·1.021^t

p'(10) ≈ 0.99954 ≈ 1.00 . . . . millions per year
