In Mathematics, the inverse function of exponentiation is known as logarithmic functions or log functions. In this article, the value of log from 1 to 10 in terms of both common and natural logarithmic functions is explained in detail.
Logarithmic Function and its Types
The logarithm is defined as a quantity that represents the power in which the base (fixed number) is raised to produce a given number. The general representation of the logarithmic function is
f(x) = loga x
In general, the two different types of logarithmic functions are
- Common Logarithmic Function
- Natural Logarithmic Function
In common logarithmic function, the base of the logarithmic function is 10. Log10 or log represents this function.
In natural logarithmic function, the base of the logarithmic function is e. Loge or ln represents this function.

Solved Examples
Example 1:
Find the value of log10(75/16) – 2 log10(5/9) + log(32/243).
Solution:
We know that loga mn = n loga m
loga (p/q) = loga p – loga q
loga (mn) = loga m + loga n
using these logarithmic rules we have,
log10(75/16) – 2 log10(5/9) + log(32/243) = log10(75/16) – log10(5/9)2 + log(32/243)
= log10(75/16) – log10(25/81) + log(32/243)
= log10 (75/16) – log10(25/81) + log(32/243)
= log10 [(75/16) × (32/243)] – log10 (25/81)
= log10 (50/81) – log10 (25/81)
= log10 [(50/81)/(25/81)]
= log10 [(50/81) × (81/25)]
= log10 2 = 0.3010
∴ log10(75/16) – 2 log10(5/9) + log(32/243) = 0.3010.
Example 2:
Evaluate log10 (124416).
Solution:
log10 (124416) = log10 (512 × 243)
= log10 (29 × 35)
= log10 29 + log10 35
= 9 log10 2 + 5 log10 3
= 9 × 0.3010 + 5 × 0.4771
= 2.709 + 2.3855
= 5.0945
∴ log10 (124416) = 5.0945.
Example 3:
Find the value of log2 10.
Solution:
By the base change rule logb (a) = 1 / loga (b)
Thus log2 10 = 1 / log10 2
= 1 / 0.3010 = 3.3223.
