SUMMARY

The discussion focuses on rearranging the energy decay equation E(t) = Eo*e^(-t/T) to solve for E(t). The user initially attempted to apply the natural logarithm incorrectly, leading to confusion. The correct approach involves understanding the properties of logarithms, specifically that ln(e^x) = x and the logarithm of a product. Clarifying these concepts is essential for successfully manipulating the equation.

Hi, I'm having trouble rearranging this equation, solving for E(t):

E(t) = Eo*e^(-t/T)

My attempt:

ln E(t) = Eo * (-t/T) and now I'm stuck.

Any help would be appreciated!

The logarithm of the right side is incorrect.

What is the logarithm of a product?
What is the logarithm of e raised to some power?

Please review the answers to these two questions.
