Based on the properties of logarithms, Sam's justification for the third step would be [tex]log_{b} ( b ^{x} ^{+} ^{y})[/tex] power rule of exponents.
Why would this be the third step?
When multiplying bases that are the same but with different exponents, the exponents should be added.
= [tex]log_{b} (b^{x} . b^{y})[/tex]
Can be written as:
= [tex]log_{b} ( b ^{x} ^{+} ^{y})[/tex]
In conclusion, option C is correct.
