Q. Solve the following logarithm problem for the positive solution for x.log2x=−5Answer:
Understand Problem: Understand the problem and the logarithmic equation.We need to find the value of x such that log2(x)=−5. This means we are looking for the number x that, when 2 is raised to the power of −5, equals x.
Convert to Exponential: Convert the logarithmic equation to an exponential equation.Using the definition of a logarithm, we can rewrite the equation log2(x)=−5 as an exponential equation: 2−5=x.
Calculate Value: Calculate the value of 2 raised to the power of −5. 2−5 is the same as 1/(25). Since 25=32, we have 1/32 as the value for x.
Verify Solution: Verify that the solution is positive.Since 321 is a positive number, we have found the positive solution for x.
