Decimal logarithm call function for calculation of an unknown exponent in which number ten is built. More often we deal with this function as with a component of physical or mathematical formulas, but sometimes it is necessary to make also practical calculations. If you have an opportunity to use the computer, then, certainly, no difficulties with finding of value of a decimal logarithm should arise.
Instruction
1. Seize, for example, the computing opportunities of the Google search engine - in the presence of Internet access it is, perhaps, the fastest of possible ways of calculation of decimal logarithms. The procedure of use of the searcher is simplest - pass to its homepage, gather lg and through a gap enter number which decimal logarithm interests you. Google will make calculation and will display result on the page. If instead of designation of LG you gather "a decimal logarithm", then and such indication of mathematical operation will be well understood search engine.
2. Use the application installed together with the operating system imitating the calculator if there is no Internet access. In Windows OS it can be caused by means of dialogue of start of programs - press a combination of the keys win + r, gather calc (a name of the file of this program without expansion) and click on the OK button. In the OS main menu there is a reference to start of this application too - look for it in the section "Standard" of the subsection "Office" from the section "All Programs". This reference and is called - "Calculator".
3. Press a combination of the alt keys + 2 to switch the application to the "engineering" mode. In earlier versions of Windows it is called "scientific" - such line can be found in the section "Look" of the menu of this program.
4. Enter number which decimal logarithm interests you. It is possible to do it as from the keyboard, and clicking a mouse on the corresponding buttons in the interface of the calculator on the monitor screen. Pay attention that here for designation of function of calculation of a decimal logarithm the inscription log, but not habitual to us is used by LG. Click the button with log symbols - the calculator will calculate and will display result.
