Things you should know how to do after today:

• Use laws of logarithms to help you solve equations involving logarithms
• Use the definition of a logarithm to help solve equations of the form:
  \[\log _a b = x\]
• Solve equations of the form:
  \[\log a = \log b\]
• Solve exponential equations using logarithms when:
  • there are different bases that are not powers of a common base
  • the variable is in the exponent
• Use an exponential equation where the variable is in the exponent to model problems and solve using logarithms
