21 ώρες 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.
Introduction. In this unit we are going to be looking at logarithms. However, before we can deal with logarithms we need to revise indices. This is because logarithms and indices are closely related, and in order to understand logarithms a good knowledge of indices is required.
The laws of logarithms. The three main laws are stated here: . First Law. log A + log B = log AB. . This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB. For example, we can write. log10 5 + log10 4 = log10(5 × 4) = log10 20.
