Decimal logarithms are applied at the solution of the equations containing unknown indicators of degrees. From the name of this type of logarithms follows that its basis is number ten. The decimal logarithm defines in what degree it is necessary to build ten to receive the argument specified in it. Calculation of such logarithms in the presence of the computer does not represent complexity.
Instruction
1. Use, for example, the Google search engine for calculation of a decimal logarithm. This searcher has the built-in calculator which is very simple in use, does not demand to understand its interface and to start any additional programs. Everything that from you it is required - to pass to the website of Google and to enter the corresponding inquiry into the only field on this page. For example, for calculation of a decimal logarithm for number 900 enter into the field of a search query lg 900 and at once (even without pressing of the button) receive the answer 2.95424251.
2. Use the calculator if there is no access to the search engine. It can be also the program calculator from the Windows OS standard set. The easiest way to start it - to press a combination of the keys WIN + R, to enter the calc team and to click the OK button. Other way is to open the menu on the Start-up button and to select in it the All Programs item. Then it is necessary to open the section "Standard" and to pass into the subsection "Office" to click there the link "Calculator". When using Windows 7 OS it is possible to press the WIN key and to enter "Calculator" into the field of search, and then to click the corresponding link in search results.
3. Switch the interface of the calculator to the expanded mode as operation necessary to you is not provided in the basic option opened by default. For this purpose open the section "Look" in the menu of the program and select item "scientific" or "engineering" - depending on that which the version of the operating system is installed in your computer.
4. Enter number for which decimal logarithm needs to be calculated, and then click the button with the inscription log - in this calculator the function of calculation of a decimal logarithm is designated quite so, but not lg. The program will count and will display result.
