Q. Solve for the exact value of x.log6(5x)−3log6(5)=1Answer:
Apply Power Rule: Apply the power rule of logarithms to simplify the term with the coefficient.The power rule states that alogb(c)=logb(ca), where a is a coefficient, b is the base of the logarithm, and c is the argument of the logarithm. In this case, we can rewrite 3log6(5) as log6(53).log6(5x)−log6(53)=1
Combine Logarithmic Terms: Use the property of logarithms that allows us to combine the two logarithmic terms into a single term by division. logb(a)−logb(c)=logb(ca), where b is the base of the logarithm, a and c are the arguments of the logarithms. We apply this property to combine the two terms.log6(535x)=1
Simplify Argument: Simplify the argument of the logarithm. 535x simplifies to 52x, since 535x is the same as 5x×5−3, which simplifies to 52x.log6(25x)=1
Convert to Exponential: Convert the logarithmic equation to an exponential equation.If logb(a)=c, then bc=a. We apply this property to solve for x.61=25x
Solve for x: Solve for x by multiplying both sides of the equation by 25.x=6×25x=150
