Q. Solve for the exact value of x.log4(9x)−4log4(3)=0Answer:
Apply power rule: Apply the power rule of logarithms to simplify the term with the coefficient.The power rule of logarithms states that nlogb(a)=logb(an). Let's apply this to the term 4log4(3).4log4(3)=log4(34)
Calculate value: Calculate the value of 34. 34=3×3×3×3=81
Rewrite equation: Rewrite the equation using the result from Step 2.log4(9x)−log4(81)=0
Apply quotient rule: Apply the quotient rule of logarithms to combine the logarithms.The quotient rule of logarithms states that logb(a)−logb(c)=logb(ca). Let's apply this to combine the logarithms.log4(819x)=0
Simplify fraction: Simplify the fraction inside the logarithm. 819x=9xSo, log4(9x)=0
Convert to exponential: Convert the logarithmic equation to an exponential equation.If logb(a)=c, then bc=a. Let's apply this to solve for x.40=9x
Calculate value: Calculate the value of 40.40=1
Solve for x: Solve for x.9x=1x=9
