The property that must be used in all the proofs is: logb(b^y) =y
<h3>What are the proofs or rules of logarithms?</h3>
The proofs are statements that are used to validate or invalidate a logarithmic expression
There are several proofs of logarithms; some of them are:
- Product rule
- Quotient rule
- Power rule
- Change of base
The common property in the first three proofs (listed above) is:
![\log_b(b^y) =y](https://tex.z-dn.net/?f=%5Clog_b%28b%5Ey%29%20%3Dy)
This is so because, it links all the three proofs
