Section 5.6 Laws of Logarithms (Day 1)

Laws of Logarithms:. let b be a positive number other than one Laws of Logarithms: let b be a positive number other than one let M and N be positive real numbers

Beware!!!!

Ex. 1: Express in terms of log M and log N:

Ex. 2: Express as a rational number or single logarithm: (work backwards)

Ex. 2: Express as a rational number or single logarithm:

Helpful log values: (You may need to substitute these into log expressions)

Ex. 3: Simplify: (ln y=k and ek=y) (log y=k and 10k=y)

Homework: p200 (w) #2-22 even 24-28 even (a and c only)
