Answer:
The solution is 
Step-by-step explanation:
The inverse of the ln function is the exponential, which means that to solve this question, we apply the exponential to both sides.
We have that:

Applying exponential to both sides:


![x = \sqrt[4]{e^6}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B4%5D%7Be%5E6%7D)


The solution is 
Answer: t=6 hours
Step-by-step explanation:
For this problem, we are given the values for r and d. We can directly plug those values in and solve for t.
450=75t [divide both sides by 75]
t=6 hours
Now, we know that there are t=6 hours.
Answer:
1
Step-by-step explanation:
note that i =
, thus
i² = (
)² = - 1
= i² × i² = - 1 × - 1 = 1
