Answer:
To help in solving exponential equations when relating the bases cannot be used
Step-by-step explanation:
Recall an equation of the form
from the expression 
, 
is the base and the power is 
.
it is impossible to carryout the operation since the bases are not equal.
This is where we implore the help of logarithm which help us to bring the base to a come base i.e using the property below
.
Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.
Use A = P (1 + r/n) ^(nt). Assuming that we're dealing with years here, n = 1, so we have
A = P (1 + r) ^(t), where r is the interest rate as a decimal fraction.
The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988.
Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.
10 miles in since they turned around, but if your adding then its 70 miles
