Rewrite as an equation.log3(27)=xlog3(27)=xRewrite log3(27)=xlog3(27)=x in exponential form using the definition of a logarithm. If xx and bb are positive real numbers and bb does not equal 11, then logb(x)=ylogb(x)=y is equivalent to by=xby=x.3x=273x=27Create equivalent expressions in the equation that all have equal bases.3x=333x=33Since the bases are the same, the two expressions are only equal if the exponents are also equal.x=3x=3The variable x is equal to 33.3
