Solving Logarithmic Equations TS: Making decisions after reflection and review. Obj: Be able to solve equations involving logarithms Warm-Up: Solve for x 1)4 x = 64 2)log 2 x + log 2 x = 6

Solve Each Equation 1)(½) x = 322) e x +2 = 3 3) 2 x = 0

Solve Each Equation 4) 3 x + 2= 215) 2 2x + 2 x – 6 = 0

Solve Each Equation 6) 8 -2 – x = 4317)e 2x – 3e x + 2 = 0

Solve Each Equation 1)2log 5 3x = 42)log 3 (5x – 1) = log 3 (x+7)

Solve Each Equation 3) 5 + 2lnx = 44) ln(x – 2) + ln(2x – 3) = 2lnx

Solve Each Equation 5) log 3 x + log 3 (x – 8) = 2
