Math Problem Statement

Solve the logarithmic equation log_3(x - 1) = 2.

Solution

The problem asks to solve the logarithmic equation:

log3(x1)=2\log_3(x - 1) = 2

To solve this equation, follow these steps:

  1. Rewrite the equation in exponential form: x1=32x - 1 = 3^2

  2. Simplify: x1=9x - 1 = 9

  3. Solve for xx: x=9+1=10x = 9 + 1 = 10

Solution:

x=10x = 10

Tip:

Remember, to convert from logarithmic to exponential form, logb(a)=c\log_b(a) = c translates to bc=ab^c = a. This is essential when solving logarithmic equations.
