In other words, the expression $\log(x)$ means ${\log}_{10}(x)$. We call a base $-10$ logarithm a common logarithm. Common logarithms are used to measure the Richter Scale mentioned at the beginning of the section. Scales for measuring the brightness of stars and the pH of acids and bases also use common logarithms.Well, if 2 to the third power is 8, 8 to the one-third power is equal to 2. So x is equal to 1/3. 8 to the one-third power is equal to 2, or you could say the cube root of 8 is 2. So in this case, x is 1/3. This logarithm right over here will evaluate to 1/3. Fascinating. Let's mix it up a little bit more. Let's say we had the log base 2.To solve this logarithm, we need to know how to read a logarithm. A logarithm is the inverse of an exponential function.

Here is a set of practice problems to accompany the Solving Logarithm Equations section of the Exponential and Logarithm Functions chapter of the notes for Paul Dawkins Algebra course at Lamar University.How To: Given an exponential equation Of the form bS =bT b S = b T, where S and T are algebraic expressions with an unknown, solve for the unknown. Use the rules of exponents to simplify, if necessary, so that the resulting equation has the form bS = bT b S = b T. Use the one-to-one property to set the exponents equal to each other.Here is the definition of the logarithm function. If b b is any number such that b > 0 b > 0 and b ≠ 1 b ≠ 1 and x >0 x > 0 then, We usually read this as “log base b b of x x ”. In this definition y =logbx y = log b x is called the logarithm form and by = x b y = x is called the exponential form.Algebra 2 Algebra 1 Remind Algebra 2 Remind Algebra 2. Syllabus. ...
