B) log 322
C) log 0.05
D) ln ln represents a natural logarithm
E) ln log with base e
F) ln ln 4.7 represents ex = 4.7

3. Find x to 4 decimal places.
G) log x =
antilog represents = x
H) log x =
antilog
I) ln x =
antiln represents e = x
J) ln x =
antiln

4. Evaluate – give each answer to four decimal places
Evaluate – give each answer to four decimal places. Be careful – use parentheses!!
K) log L) 3 (log 42)
log log 13

5. Solve each exponential Function
A) 2x = 32 B) 9x = 81 C) 16 = 8x D) 2x = 1 16

6. Solve each exponential Function
E) 3x = F) 81 = 27x G) 97 = 3x H) 273 = 9x

7. Solve each exponential Function
I) 24x – 3 = 82x – 4 J) 52x + 1 = 1253x-4
K) 9x+3 = 273x L) 10x = 0.01
