Q. Solve for the exact value of x.log6(8x)−3log6(3)=0Answer:
Apply Power Rule: Apply the power rule of logarithms to simplify the equation.The power rule states that alogb(c)=logb(ca), where a is a constant, b is the base of the logarithm, and c is the argument of the logarithm. We can apply this rule to the term 3log6(3) to simplify the equation.log6(8x)−log6(33)=0log6(8x)−log6(27)=0
Combine Logarithmic Terms: Combine the logarithmic terms using the quotient rule.The quotient rule states that logb(m)−logb(n)=logb(nm), where b is the base of the logarithm, m and n are the arguments of the logarithm. We can combine the two logarithmic terms into a single logarithm.log6(278x)=0
Convert to Exponential: Convert the logarithmic equation to an exponential equation.The definition of a logarithm states that if logb(m)=n, then bn=m. We can use this definition to convert the logarithmic equation into an exponential equation.60=278x
Solve for x: Solve for x.Since 60=1, we can multiply both sides of the equation by 27 to solve for x.1=278x27=8xx=827
