1 ημέρα πριν · Log Rules: The Product Rule. The first of the natural log rules that we will cover in this guide is the product rule: logₐ (MN) = logₐM + logₐN. Figure 03: The product rule of logarithms. The product rule states that the logarithm a product equals the sum of the logarithms of the factors that make up the product.
logarithms allow for the simplification of complex problem situations to basic arithmetic operations. In this unit you will examine the definition and inverse relationship with the exponential function, practice the laws of logarithms, solve logarithmic equations, and explore a

Introduction To Logarithms. Logarithms were originally developed to simplify complex arithmetic calculations. They were designed to transform multiplicative processes into additive ones. If at first this seems like no big deal, then try multiplying 2,234,459,912 and 3,456,234,459. Without a calculator !
1.2 Logarithms We use can logarithms to solve exponential equations: The solution of ax = b is x = log a b For example, the solution of ex = 2 is x = log e 2. To find the value of this logarithm, we need to use a calculator: log e 2 = 0.6931. Note Logarithms were invented and used for solving exponential equations by the Scottish baron
