8.2 Properties of Logarithms

Evaluate using properties of logarithms (no calculator):  $\log_64\ +\ \log_654$  

(a)  

Expand the logarithm.

• A
• B
• C
• D

• log (a⁵ + b²⁵)
• log (a⁵ − b²⁵)
• log (ab²⁵)
• log (a⁵/b²⁵)

Rewrite log_b(xⁿ)

• nlog_bx
• (log_bx)ⁿ
• xⁿlog_bx
• log_b(xⁿ)

True or False:

log 12 - log 4 = log 8

• True

• False

• logx³y³z³
