9-158.
  1. Solve each equation. Homework Help ✎

    1. log3(2x − 1) = −2

    2. 5log5 (x) = 3

    3. log2(x) − log2(3) = 4

    4. log3(5) = x

Convert the equation into exponential form.
3−2 = 2x − 1

Now solve for x.

Remember the rule b logb(N) = N

x = 3

Remember the rule that log(N)−log(M) = log(N/M).

3x = 5
