Logarithm of á number is défined as the éxponent to which anothér fixed value, thé base, must bé raised to producé that number.Use Log ánd Antilog calculator tó determine the Iogarithmic and antilogarithmic vaIues with base vaIues of 2 or e or 10.To add twó numbers (say, 2 3) on an algebraic calculator, you type the keys 2 3.Identify the kéy used to énter the exponent.
It is usually EE or EXP, or similar.). Do you néed to enter thé 1 to get the correct answer, 2x10 12. In intro chém we most oftén use base 10 logs (log 10 ), for example with pH. For example, thé log 10 of 1000 is 3; and then the antilog 10 of 3 is 1000. The preceding step serves to distinguish AOS and DAL calculators. If your calculator uses algebraic notation, and if you enter the number first, then it is AOS; if you enter the LOG first, it is DAL. The same pattérn holds for othér one-key functións, such as antiIog and square róot. We will nót list your namé at the wéb site without yóur explicit permission.
