2
Algebra II 7.6: Solve Exponential and Logarithmic Equations HW: tonight: p.543 (2-8 even, 13-15 all) Monday: 7.6: p.519-520 (4-14 even, 24-36 even) Test: Wednesday, 3/4

3
7.5: Change-of-base Formula

4
Use the change-of-base formula to evaluate the logarithm.

5
Property of Equality for Exponential Equations

7
Solve the equation. (Type 1) If the equation is a log = log with the same base, make the expressions equal and solve. 4x – 7 = x + 5 3x = 12 x = 4

8
Solve the equation. (Type 1)

9
Algebra II 7.6: Solve Exponential and Logarithmic Equations HW: 7.6: p.519-520 (4-14 even, 24-36 even) Test: Wednesday, 3/4

10
Solve the equation. (Type 2) If the equation is a log = number, then write as a power.

11
Solve the equation. (Type 2)

12
Solve the equation. (Type 3) Rewrite the equation so that the powers have the same base. When the equation is a power = power with the same base, make the exponents equal and solve.

13
Solve the equation. (Type 3)

14
Solve the equation. (Type 4) If the equation is a power = number, then rewrite as a log. Solve equation using log rules. (change of base)

15
