Section 6-5: Properties of Logarithms (Part 2)
April-May
28-1 Target 6B We are learning the properties of logarithms so that we can solve logarithmic equations. The properties from last week will help us to evaluate logs that are not base 10 Product Property log log logb b bm n mn+ Quotient Property
log log logb b bmm nn
Power Property
log lognb bm n m
To evaluate, we will use the values given to us for each set of problems. In addition to the ones that are given to use, we can always use
𝒍𝒐𝒈𝒃𝟏 = 𝟎 This will work no matter what number you are given for the base
Use 𝐥𝐨𝐠𝟐 𝟑 = 𝟏. 𝟓𝟖𝟓 and 𝐥𝐨𝐠𝟐 𝟕 = 𝟐. 𝟖𝟎𝟕 to evaluate each logarithm. 1. log2 21 2. log2 3. log2 49 Use 𝒍𝒐𝒈𝟔𝟓 = 𝟎. 𝟖𝟗𝟖 and 𝒍𝒐𝒈𝟔𝟖 = 𝟏. 𝟏𝟔𝟏 to evaluate each logarithm. 4) 𝑙𝑜𝑔 5) 𝑙𝑜𝑔 40 6) 𝑙𝑜𝑔 1 7) 𝑙𝑜𝑔 125 8) 𝑙𝑜𝑔 64 9) 𝑙𝑜𝑔 1

A2 4.28 – 5.1 Practice (Properties of logarithms Part 2)
Use 4log 12 1.1 , 4log 7 0.8 and 4log 8 0.9 to evaluate each logarithm.
