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
 from the expression  ,
,  is the base and the power is
 is the base and the power is  .
. 
 it is impossible to carryout the operation since the bases are not equal.
 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.

Answer:
8 records were sold on Wednesday, and 24 records were sold on Thursday
Step-by-step explanation:
Let's call the number of records sold on Wednesday w, and the number sold on Thursday t.
t+w=32
t=3w
Substituting:
(3w)+w=32
4w=32
w=8
t=3w=3(8)=24
Hope this helps!
