Respuesta :
Proofs are used to confirm or disprove mathematical statements
The missing expression in the proof is : [tex]\log_b((b^{xy})[/tex]
How to complete the proof
From the question, the first two steps are:
[tex]\log_b(M^y)[/tex]
[tex]\log_b((b^x)^y)[/tex]
By the properties of exponents, we have:
[tex]\log_b((b^{xy})[/tex]
The above expression represents the missing expression in the proof of the logarithmic expression
Hence, the missing expression is : [tex]\log_b((b^{xy})[/tex]
