Answer:
To help in solving exponential equations when relating the bases cannot be used
Step-by-step explanation:
Recall an equation of the form
[tex]a^{x}=b\\[/tex] from the expression [tex]a^{x}\\[/tex], [tex]a\\[/tex] is the base and the power is [tex]{x}\\[/tex].
[tex]a\neq b\\[/tex] 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
[tex]loga^{x}=logb\\x=\frac{logb}{loga} \\[/tex].
Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.
