Use of the property of logarithms solve for the value of x for log 3 x.

Class 9 math logarithm table 1 to 100. The table below lists the common logarithms with base 10 for numbers between 1 and 10. In the same fashion since 10 2 100 then 2 log 10 100. Ml aggarwal class 9 solutions for icse maths chapter 9 logarithms. It is called a common logarithm.

Logarithm the exponent or power to which a base must be raised to yield a given number. Therefore 3 is the logarithm of 8 to base 2 or 3 log 2 8. It is how many times we need to use 10 in a multiplication to get our desired number. So 2 is the exponent value and the value of log 10 100 2.

X log 10 x log 2 x log e x. Log 100 this usually means that the base is really 10. Log b x y log b x log b 1 y x log b x y log b x log b 1 y x logarithmic table. Each log table is only usable with a certain base.

Anti log can be found out from anti log table in the same manner as log the main difference is that an anti log table contains numbers from 00 to 99 in the extreme left column. It is not always necessary to find the logarithm of a number by mere calculation. For instance the first entry in the third column means that the common log of 2 00 is 0 3010300. Expressed mathematically x is the logarithm of n to the base b if b x n in which case one writes x log b n for example 2 3 8.

The most common type of logarithm table is used is log base 10. I 5 2 25 ii a 5 64 iii 7 x 100 iv 9 1. Since 2 6 2 2 2 2 2 2 64 6 is the exponent value and log 2 64 6. In this case 10 2 yields you 100.
