Exercise 18 Page 494

Start by using the Change of Base Formula.

3/2

Practice makes perfect

To exaluate the given expression, we will use the Change of Base Formula. log_c a = log_2 a/log_2 c Later, we will use the Power Property of Logarithms. Power:& log_b m^n = n log_b m

log_4 8

log_c a = log_b a/log_b c

log_2 8/log_2 4

Write as a power

log_2 ( 2^3 )/log_2 ( 2^2 )

log_2(a^m)= m* log_2(a)

3 log_2 2/2 log_2 2

log_2(2) = 1

3 (1)/2 (1)
