11-147.
  1. Rewrite each equation as an equivalent equation using log10. You do not need to find a numerical answer. These are sometimes known as change of base problems. Homework Help ✎

    1. log2(3) = x

    2. log5(8) = x

    3. log7(12) = x

    4. loga(b) = x

Write the equation in exponential form.

2x = 3

Take the logarithm of base 10.

log10(2x) = log10(3)

Use the Power Property of Logarithms and solve for x.

xlog10(2) = log10(3)
