Exponents and Logarithm

Two guys LOG and LN go for a walk through different curvy roads. Where do they meet?

Rewrite the exponential equation into its logarithmic equation; x⁶=64

• log₆x=64
• log6=64
• log₆64=x
• log_x64=6

Write in logarithmic form.
2^-4 = ¹/₁₆

• log₂(¹/₁₆) = -4
• log_-4(¹/₁₆) = 2
• log _-4 2 = ¹/₁₆
• log₂(-4) = ¹/₁₆

Which of the following models would project the value of a company worth $400,000 whose value is continuously decreasing by 8% annually?

• y=400,000e^.08t

• y=400,000e^-.08t

• y=400,000e^-8t

• y=400,000e^8t
