Logarithms that accept 10 main numbers are called ordinary. One means to nurture one's hear the ordinary logarim value of a publish is to piece of job the attention of logarithmic dafar. In the logarithmic list, alone the mantise (decimal publish of logarima retrieval results) is created hence that the index publish or the feature (integer of the logarithmic picking result) must hold upward determined first.
1. Finding Logarithmic Results from Numbers Between 1 as well as 10
Since log 1 = 0 as well as log 10 = 1 as well as then the 10 based logarithms of the numbers betwixt 1 as well as 10 volition prevarication betwixt 0 as well as 1. So the index or its feature 0. Suppose log 2.345 has the index / feature 0. The numbers behind the comma are mantise tin move hold upward obtained from the listing of logarithms where the business 234 column 5 obtained publish 3701. Notice the gamber logarithm tabular array below:
So log 2,345 = 0.3701
2. Looking for Logarithmic Results of Numbers More Than 10
Log 10 = 1 as well as log 100 = 2, as well as then the 10 based logarithms of the numbers betwixt 10 and 100 will prevarication betwixt 1 and 2. So the index or its characteristics 1.Log 100 = 2 as well as log chiliad = 3, the base of operations logarithm 10 of the numbers betwixt 100 and 1000 will prevarication betwixt 2 as well as 3. So the index or its characteristics 2 and hence on.
Example:
Determine the logarithm value of log 19.69!
Answer:
The index of 19.69 is 1, its mantise is obtained from the listing of rows 196 column 9 and in that place is a publish 2942. Thus, log 19.69 is 1.2942.
3. Finding Logarithmic Results of Numbers Less than 1
Characteristics from 0.1 to 1 are -1Characteristics of 0.01 to 0.1 are -2
Characteristics from 0.001 to 0.01 are -3, as well as hence on
Example:
Please nurture one's hear the logarithm value of log 0.9272!
Answer:
The index of 0.9272 is -1, its mantise is obtained from the listing on business 927 column 2 and in that place are 9672 numbers. Thus, log 0.927 = 0.9672 - 1 = -0.0328
Similarly this article.
Sorry if in that place is a incorrect word.
