Math Problem Statement

Solve for x: log_x(27) = 3

Solution

The given problem is to solve for xx in the equation:

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

Step-by-Step Solution:

  1. Recall the logarithmic definition: loga(b)=cmeansac=b\log_a(b) = c \quad \text{means} \quad a^c = b

    Here, a=xa = x, b=27b = 27, and c=3c = 3. Using this definition: x3=27x^3 = 27

  2. Solve for xx: x=273x = \sqrt[3]{27}

    The cube root of 2727 is 33, so: x=3x = 3

Final Answer:

x=3x = 3
