Obj: Expanding Logarithms
Condensing Logarithms
Laws of Logarithms
Product: loga (AB) = loga (A) + loga (B)
Quotient: Power: loga(AC) = C * loga (A)
***Same laws for natural logs***

Expanding Logs
• Apply the laws of logs to rewrite a single logarithmic term as an expression of logarithmic terms.
• Each term will have the same base.
• The number of factors in the original expression will be the number of terms in the expanded expression.

EX. – Expand the following.
Laws:
loga (AB) = loga (A) + loga (B)
• 1. log2 (6x)
• 2. log7 (3xy5)
loga(AC) = C * loga (A)

Condensing Logs • Apply the laws of logs to rewrite a logarithmic expression as a single logarithmic term.
• The number of terms in the log expression represent the number of factors in the single log term.
• You can ONLY condense log terms that have the same base!!!

EX. – Condense the following:
• log4 2 + log4 32 • 3. 3log(7x + 6)
• log(4x) – log (7)
• 4. 2 log(x) + log (x – 1)
