How do you solve logx = 3? | Socratic
WEBNov 20, 2015 · How do you solve log x = 3? Precalculus Solving Exponential and Logarithmic Equations Logarithmic Models. 1 Answer. mason m. Nov 20, 2015. x = 1000. Explanation: Note that when log is not paired with a base, there base is implied to be 10. So, logx can be written as log10x. log10x = 3. 10log10x = 103. x = 1000. Answer link.
Log Calculator (Logarithm)
WEB2 days ago · Find the logarithm with base 10 of the number 100. lg (100) = 2. Find the logarithm with base 10 of the number 2. lg (2) = 0.30103. Divide these values by one another: lg (100)/lg (2) = 2 / 0.30103 = 6.644. You can also skip steps 3-5 and input the number and base directly into the log calculator.

WEBFrom the change of base theorem, log base a of b = (ln b)/(ln a). For example, you can calculate log base 3 of 5 by calculating (ln 5)/(ln 3) which should give approximately 1.465. (Note that if your calculator also has a log key, another way to calculate log base 3 of 5 is to calculate (log 5)/(log 3). You should still get about 1.465.)

WEBlog b x = y with b being the base, x being a real number, and y being an exponent. For example, 2 3 = 8 ⇒ log 2 8 = 3 (the logarithm of 8 to base 2 is equal to 3, because 2 3 = 8).
Logarithm - Wikipedia
WEBFor example, since 1000 = 10 3, the logarithm base of 1000 is 3, or log 10 (1000) = 3. The logarithm of x to base b is denoted as log b (x), or without parentheses, log b x. When the base is clear from the context or is irrelevant, such as in big O notation, it …
Intro to logarithm properties (article) | Khan Academy
WEBLogarithms, like exponents, have many helpful properties that can be used to simplify logarithmic expressions and solve logarithmic equations. This article explores three of those properties. Let's take a look at each property individually. The product rule: log b. ( M N) = log b. ( M) + log b. ( N)

WEBLet's say you had... log, base 3, of 81. What would this evaluate to? Well this is a reminder, this evaluates to the power we have to raise 3 to, to get to 81. So if you want to, you can set this to be equal to an 'x', and you can restate this equation as, 3 to the 'x' power, is equal to 81. Why is a logarithm useful?

WEBExample 1:Solve the logarithmic equation. Since we want to transform the left side into a single logarithmic equation, we should use the Product Rule in reverse to condense it. Here is the rule, just in case you forgot. Given. Apply Product Rule from Log Rules. Distribute: [latex]\left( {x + 2} \right)\left( 3 \right) = 3x + 6[/latex]
