LOGS ON THE CALCULATOR AND SOLVING EXPONENTIAL FUNCTIONS

Logs on the Calculator ◦ Find the following: ◦ A) log 3. 07 log 3. 07 represents 10 x = 3. 07 ◦ B) log 322 ◦ C) log 0. 05 ◦ D) ln 4. 7 ln represents a natural logarithm ◦ E) ln 65 log with base e ◦ F) ln 6500 ln 4. 7 represents e x = 4. 7

Find x to 4 decimal places. ◦ G) log x = 2. 9263 ◦ antilog 2. 9263 represents 10 2. 9263 = x ◦ H) log x = - 0. 2984 ◦ antilog - 0. 2984 ◦ I) ln x = 2. 6932 ◦ antiln 2. 6932 ◦ J) ln x = -0. 1542 ◦ antiln -0. 1542 represents e 2. 6932 = x

Evaluate – give each answer to four decimal places. Be careful – use parentheses!! ◦ K) 3 + log 2 L) 3 (log 42) ◦ log 5 1 + log 13
