  1. Algebra II 8-5 Notes

  2. Rules of Logarithms Product Property: logbxy = _______ + ________ Quotient Property: logbx/y = _______ - _______ Power Property: logbun = ___________

  3. Properties of Logarithms Use log53 = 0.683 and log57 = 1.209 to approximate: log53/7= log521 = log549 =

  4. Expand Expand the following: log34x2 b. log3x y ln5x2 y3

  5. Condense Condense the following: log6 + 2log2 – log3 3lnx - 2lny +5lnz 3(log23 – log2x) + (log2x – log29)

  6. Change of Base Formula logcu = logu and logcu = lnu logclnc Therefore log512 = =

  7. Evaluate the following log724 log531/3 log225 =
