Answer:
r = 0.52 to the nearest hundredth
Step-by-step explanation:
Here, given that ;
e^4r = 8
We want to find the value of r
To do this, we will need to find the ln of both sides
Mathematically;
ln(e^4r) = ln 8
4r ln e = ln 8
Mathematically; ln e = 1
Thus;
4r = ln 8
4r = 2.07944154168
r = 2.07944154168/4
r = 0.51986038542
To the nearest hundredth, r = 0.52
