WebExpanding Logarithms. Taken together, the product rule, quotient rule, and power rule are often called “properties of logs.”. Sometimes we apply more than one rule in order to expand an expression. For example: logb(6x y) = logb(6x)−logby = logb6+logbx−logby l o g b ( 6 x y) = l o g b ( 6 x) − l o g b y = l o g b 6 + l o g b x − l o ... WebHow To: Given a logarithm of the form y = logb(x) y = l o g b ( x), evaluate it mentally Rewrite the argument x as a power of b: by = x b y = x. Use previous knowledge of powers of b to …
