Q. Solve the following logarithm problem for the positive solution for x.logx64=56Answer:
Understand the logarithmic equation: Understand the logarithmic equation.The given logarithmic equation is logx(64)=56. This means that x raised to the power of 56 equals 64.
Convert to exponential form: Convert the logarithmic form to exponential form.Using the definition of a logarithm, we can rewrite the equation in its exponential form: x56=64.
Find the 5th root: Find the 5th root of both sides.To isolate x6, we take the 5th root of both sides of the equation: (x(6/5))(5/6)=64(5/6).
Simplify the equation: Simplify the equation.The left side simplifies to x, and the right side simplifies to the 5th root of 64 raised to the 6th power: x=(645/6).
Calculate the 5th root of 64: Calculate the 5th root of 64.The 5th root of 64 is 2 because 25=32 and 45=1024, so 64 must have a 5th root between 2 and 4. Since 26=64, we know that 2 is the 5th root of 64.
Raise to the 6th power: Raise the 5th root of 64 to the 6th power.Now we raise 2 to the 6th power: 26=64.
Write final answer: Write down the final answer.Since x=6465 and we have found that 6465=26=64, the positive solution for x is 2.
