Question

log a base 1 not define why?​

Answer 1

Answer:

Calculating logarithm of an expression with a base 1 is pointless. Log of a number is the power to which the base should be raised to get the number. ... The expression says (a) raised to the power x gives N. So if you take the base as 1, 1 raised to the power of anything would give you 1.

Answer 2

Answer:

log a with base 1 is not defined because there is no such value on exponent of 1 to result a value which is not equal to 1.

For example if value of a is 3 then there is no such value on exponent on 1 which results in 3.

Not defined in simple words means not present. There is no such value present in universe.
