Final answer:
The equation log₅(a/b²)log₅a-2log₅b simplifies to log₅(a³b) and is true for all possible values of the variables.
Step-by-step explanation:
The given equation is:
log₅(a/b²)log₅a-2log₅b
To determine whether this equation is true for all possible values of the variables, we can simplify it using logarithmic properties.
First, we can use the property log₋a-log₋c = log₅(a/b) to rewrite the equation as:
log₅(a/b²) + log₅a - 2log₅b
Next, we can use the property log₅a + log₅b = log₅(ab) to combine the terms:
log₅((a/b²)(ab²))
Simplifying further, we have:
log₅(a³b)
Therefore, the given equation simplifies to log₅(a³b) and is true for all possible values of the variables.
