Answer:

\frac{\ln(2x + 5)}{\ln(x - 3)} = 0

Step-by-step explanation:

Data provided in the question:

In(2x + 5) = In(x - 3)

we can rearrange the above equation as

⇒ In(2x + 5) - In(x - 3)  = 0

now,

from the properties of natural log function, we know that

\ln(\frac{A}{B}) = \ln(A)-\ln(B)

therefore,

we get

\frac{\ln(2x + 5)}{\ln(x - 3)} = 0

Hence,

Expression as the logarithm of a single quantity is \frac{\ln(2x + 5)}{\ln(x - 3)} = 0

Simplify the logarithm.

In(2x + 5) = In(x - 3) → In(2x + 5) - In(x - 3) = 0

Use the quotient rule [ \text{ln}\frac{a}{b} = \text{ln(a)}-\text{ln(b)} ] to simplify.

In(2x + 5) - In(x - 3) = 0 → \frac{\text{ln(2x + 5)}}{\text{ln}(x - 3)}=0

Therefore, the  logarithm as a single quantity is \frac{\text{ln(2x + 5)}}{\text{ln}(x - 3)}=0

Best of Luck!
