Raising the logarithm of a number to its base is equal to the number. Learn the eight (8) log rules or laws to help you evaluate, expand, condense, and solve logarithmic equations. Try out the log rules practice problems for an even better understanding.

Use the rules of logarithms to rewrite this expression in terms of logx and logy. Now, apply the quotient rule and then the power rule. Formula and example problems for the product rule, quotient rule and power rule. Also, free downloadable worksheets on these topics.

Logarithm: the number of times a base must be multiplied by itself to reach a given number. Logarithmic equation: the inverse of an exponential equation with base b. y = y logb x has an exponential counterpart of x = b . Common logarithm: a logarithm with a …

Examples of Logarithms 1) Write t y = x in logarithmic notation. Note: by = x is equivalent to 𝑙 𝑔 b :x ; = y. t =x in logarithmic notation is 𝑙 𝑔2 :x ;=y. 2) 𝐄 𝐚𝐥 𝐚 𝐞 𝒍 𝒈 :𝟖 ;. Note:8= t3. 𝑙 𝑔2 :8 ;= 𝑙 𝑔2 : t3 ;= u∙𝑙 𝑔2 : t ;= u∙ s= u Thus, 𝑙 𝑔2 :8 ;= u.

Use the Power Rule for Logarithms. Since 7a is the product of 7 and a, you can write 7a as 7 • a. Use the Product Rule for Logarithms. 5 3 log = log511 – log53 Use the Quotient Rule for Logarithms. The following examples use more than one of the rules at a time. 2 c . The answer is 2•log2a + log2b – log2c.

Logarithm Rules. The base b logarithm of a number is the exponent that we need to raise the base in order to get the number. Logarithm definition; Logarithm rules; Logarithm problems; Complex logarithm; Graph of log(x) Logarithm table; Logarithm calculator; Logarithm definition. When b is raised to the power of y is equal x: b y = x
