See All Math Topics Home > Pre-Algebra > Logarithm Logarithm Worksheets Logarithm worksheets in this page cover the skills based on converting between logarithmic form and exponential form, evaluating logarithmic expressions, finding the value of the variable to make the equation correct, solving logarithmic equations, single logarithm, expanding logarithm using power rule, product rule and quotient rule, expressing the log value in algebraic expression, logarithms using calculator and more.
Logarithmic and Exponential Form There are two sections in each worksheet. Only Numerals: Sheet 1 | Sheet 2 | Sheet 3 Numerals & Variables: Sheet 1 | Sheet 2 | Sheet 3 Evaluating Expressions: Level 1 Evaluate the value of each logarithmic expression using power rule. Solving Log Equations. Solving Logarithmic Equations Remember that logaM =x means exactly the same thing as ax = M , that is, "logaM is the number to which you raise a in order to get M.
" This is the key to solving equations in which logarithms appear. For example: Suppose we want to solve the equation log2 y = 3. Since this means exactly the same thing as 23 = y, the equation pretty much solves itself!! Here's a slightly harder problem: Solve the equation log2 (5z+ 1) = 4. Exercises I Solve the following. You should see from these examples that the basic strategy is to convert the equation involving logarithms to one that doesn't involve logs (by using the equivalent exponential form of the equation), and then solving the converted equation.

(3) Rewrite so there are no logarithms of products, powers or quotients. What is a Logarithm? A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents).
For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2 because. Introduction to Logarithms. In its simplest form, a logarithm answers the question: How many of one number do we multiply to get another number?

Logarithms: Introduction to "The Relationship" (page 1 of 3) Sections: Introduction to logs, Simplifying log expressions, Common and natural logs Logarithms are the "opposite" of exponentials, just as subtraction is the opposite of addition and division is the opposite of multiplication. Logs "undo" exponentials. Technically speaking, logs are the inverses of exponentials. In practical terms, I have found it useful to think of logs in terms of The Relationship: Khanacademy. Logarithms - Topics in precalculus. Definition Common logarithms Natural logarithms The three laws of logarithms Proof of the laws of logarithms Change of base WHEN WE ARE GIVEN the base 2, for example, and exponent 3, then we can evaluate 23.
Inversely, if we are given the base 2 and its power 8 -- -- then what is the exponent that will produce 8? That exponent is called a logarithm. 3 = log28. We write the base 2 as a subscript. 3 is the exponent to which 2 must be raised to produce 8. A logarithm is an exponent. Since then log1010,000 = 4. "The logarithm of 10,000 with base 10 is 4. " 4 is the exponent to which 10 must be raised to produce 10,000. "104 = 10,000" is called the exponential form. "log1010,000 = 4" is called the logarithmic form. Here is the definition: That base with that exponent produces x. Example 1. Answer. 25 = 32. Problem 1. To see the answer, pass your mouse over the colored area.
Proper fractions. Lesson 20 of Arithmetic Example 3. Answer. 8 to what exponent produces 1? Log81 = 0. Example 4. Higher Bitesize Maths - Logarithms : Revision. Introduction to Logarithms.
