Math Problem Statement

Determine the value of the unknown: log_b 6 = 1/3. Solve for b.

Solution

We are tasked with solving for bb given:

logb6=13\log_b 6 = \frac{1}{3}

Step-by-step Solution:

  1. Understand the logarithmic form:

    The equation logb6=13\log_b 6 = \frac{1}{3} can be rewritten in its exponential form as:

    b13=6b^{\frac{1}{3}} = 6

    This means the cube root of bb equals 6.

  2. Eliminate the cube root:

    To solve for bb, cube both sides of the equation:

    (b13)3=63\left(b^{\frac{1}{3}}\right)^3 = 6^3

  3. Simplify:

    • The left-hand side simplifies to bb, since the cube and the cube root cancel.
    • The right-hand side becomes 63=2166^3 = 216.

    Thus:

    b=216b = 216

Final Answer:

b=216b = 216
