1. Mental Math
Solve for x
1) 32 3x - 2 = 16 4) log81( 1 ) = x
3
2) 1 = 64
2x-1
2
5) log8x = 3
3) 3(52x - 9) = 375

2. Log Properties/ Theorems/ Laws
single log expanded log
(M · N) = log
Extension:
log 8 = log 8

4. Use Log Laws to Evaluate Expressions
ex 1) log6 8 + log6 9 - log6 2
ex 2) log7 7√7
1
ex 3) 2log2 12 - (log2 6 + 3 log2 27)

5. Rewrite as a single log:
(x - 2) - 3log
alog3 - logx - log(a + 1)
ex 3) log7 x2 + log7 x - 5log7 x
2
