Q. Solve for the exact value of x.log6(6x)+2log6(4)=1Answer:
Apply power rule: Apply the power rule of logarithms to the second term.The power rule states that logb(ac)=c⋅logb(a). We can apply this to the second term 2log6(4) to simplify the equation.log6(6x)+log6(42)=1
Simplify second logarithm: Simplify the second logarithm.42 is 16, so we can rewrite the equation as:log6(6x)+log6(16)=1
Combine logarithms: Combine the logarithms on the left side using the product rule.The product rule states that logb(m)+logb(n)=logb(mn). We can combine the two logarithms into one.log6(6x⋅16)=1
Simplify product inside: Simplify the product inside the logarithm. 6x×16=96x, so the equation becomes: log6(96x)=1
Convert to exponential: Convert the logarithmic equation to an exponential equation.If logb(a)=c, then bc=a. We can apply this to our equation to solve for x.61=96x
Solve for x: Solve for x.Divide both sides by 96 to isolate x.x=966
Simplify the fraction: Simplify the fraction. 966 can be simplified by dividing both numerator and denominator by 6. x=161
