Q. Solve the following logarithm problem for the positive solution for x.log64x=−31Answer:
Understand the logarithmic equation: Understand the logarithmic equation.We have the equation log64(x)=−(31). This means we are looking for a number x such that when we raise 64 to the power of −(31), we get x.
Convert to exponential form: Convert the logarithmic equation to exponential form.Using the definition of a logarithm, we can rewrite the equation in exponential form: 64−(1/3)=x.
Calculate value of 64−(1/3): Calculate the value of 64−(1/3). Since 64 is 43, we can rewrite 64−(1/3) as (43)−(1/3). By the power of a power rule, this simplifies to 4−1, which is equal to 1/4.
Conclude the solution: Conclude the solution.Therefore, the positive solution for x is x=41.
