WebIf we divide a logarithm by a number, on the natural scale we take that number root. For example, log 10 10(10) and the cube root of 1,000 is 10, i.e. 10 ×10 × 10 = 1,000. Note that we are multiplying and dividing a logarithm by a plain number, not by another logarithm. Logarithms which are not whole numbers Logarithms do not have to be whole ... WebThe chapter is divided into the following: Logarithms in base 10, Logarithms in base a, Laws of logarithms, Natural logarithms, Logarithmic equations, The change of base rule, solving exponential equations using logarithms and Logarithmic functions.
