Solution 3.4:1c
From Förberedande kurs i matematik 1
The equation has the same form as the equation in exercise c and we can therefore use the same strategy.
First, we take logs of both sides,
3ex
=ln
7
2x
and use the log laws to make
lne=ln7+x
ln2
Then, collect together the
lne−ln2
=ln7−ln3
The solution is now
