You just have to add I think
Your first step when subtracting integers is (d) subtract the numbers
<h3>How to determine the first step?</h3>
The operation is given as:
Subtraction operation
Assume that the operation is a simple expression that involves subtraction, such as:
a - b
The first step is to subtract the numbers
Hence, your first step when subtracting integers is (d) subtract the numbers

Log(2)/log(1.064) ≈ 11.17 . . . . hours
_____
The population can be given by
p(n) = p₀×1.064ⁿ . . . . where n is the number of hours
You want to find n whe p(n) = 2*p₀.
2p₀ = p₀×1.064ⁿ . . . . . . . . . . . . substitute the given information
2 = 1.064ⁿ . . . . . . . . . . . . . . . . . divide by p₀
log(2) = n×log(1.064) . . . . . . . . take logs to make it a linear equation
log(2)/log(1.064) = n . . . . . . . . divide by the coefficient of n
