What is the logarithm of one?
logb(1) = ?
The logarithmic function
y = logb(x)
is the inverse function of the exponential function
x = by
The logarithm of x=1 is the number y we should raise the base b to get 1.
The base b raised to the power of 0 is equal to 1,
b0 = 1
So base b logarithm of one is zero:
logb(1) = 0
For example, the base 10 logarithm of 1:
Since 10 raised to the power of 0 is 1,
100 = 1
Then the base 10 logarithm of 1 is 0.
log10(1) = 0
