Ans: There are two types of logarithms, and they are given below: Common Logarithm The common logarithm is also known as the base ten logarithms. It is written as \(p\log \log p\) . So, when the logarithm is taken with respect to base \(10\), then we call it is the common … sports performance coachingWitryna1.5.3: Solving Exponential Statements. Logarithms are also used to solve exponential statements, statements where the variable is part of an exponent. When solving an exponential statement, we first need to isolate the exponential term. Once we have isolated the exponential term, we can take a logarithm of both sides. sports performance job openingsWitryna1. Revision of logarithms Logarithms provide an alternative way of writing expressions involving powers. If a = bc then log b a = c For example: 100 = 102 can be written as log 10 100 = 2.
