Math Problem Statement

Solve: log_x(27) = 3. Enter x as an integer or as a reduced fraction.

Solution

The question asks you to solve the equation:

logx(27)=3\log_x(27) = 3

Step-by-Step Solution:

  1. Definition of Logarithms: The logarithmic equation logx(27)=3\log_x(27) = 3 means: x3=27x^3 = 27

  2. Solve for xx: To find xx, take the cube root of both sides: x=273x = \sqrt[3]{27}

  3. Evaluate the Cube Root: The cube root of 27 is: x=3x = 3

Final Answer:

x=3x = 3
