When proving the properties of logarithms when exponents must be used, the property that is used in all of these is D. [tex]log_{b} (b^y) = y[/tex]
When proving any property of logarithms that have to do with exponents, one property that should always be used is [tex]log_{b} (b^y) = y[/tex].
Expressing y as a product of [tex]log_{b} (b^y)[/tex] is the most basic property of using exponents on logs because it has both product, quotient, and power rules of logarithms.
