Solving Logarithmic EquationsTS: Making decisions after reflection and review.Obj: Be able to solve equations involving logarithms
Warm-Up: Solve for x1) 4x = 64
2) log2x + log2x = 6
Solve Each Equation
1) (½)x = 32 2) ex +2 = 3
3) 2x = 0
Solve Each Equation
4) 3x + 2= 21 5) 22x + 2x – 6
= 0
Solve Each Equation
6) 8-2 – x = 431 7)e2x – 3ex + 2
= 0
Solve Each Equation
1) 2log53x = 4 2)log3(5x – 1) =
log3(x+7)
Solve Each Equation
3) 5 + 2lnx = 4 4) ln(x – 2) + ln(2x – 3) =
2lnx
Solve Each Equation
5) log3x + log3(x – 8) = 2
You try & use your calculator to check your answers
1) e2x – 5ex + 6 = 0
2) ln(3x + 5) = 8
3) logx25 = 2
4) lnx – ln2 = 0
5) log4(x – 20) + log4(x) = -16
6) 1000e-4x = 75
