Today In Math

Today in Math we had to take a test on Chapter 8. We were tested on exponential growth and decay, and also on logarithms. We learned the properties of Logarithms.

PROPERTIES OF LOGARITHMS
Let b, u, and v be positive numbers such that b does not equal 1

Product Property Logb uv = logb u + logb v

Quotient Property Logb u/v = logb u - logb v

Power Property Logb un = nlogb u


We learned how to use these properties to be able to solve different expressions and equations
