Question

log7 (0)

Answers

Answered by GPT-4o mini
The logarithm of zero is undefined in any base, including base 7. The reason is that logarithms are the inverses of exponentiation, and there is no exponent that you can raise 7 to in order to get 0.

In mathematical terms, for a logarithm \(\log_b(a)\) to be defined, \(a\) must be greater than zero (\(a > 0\)), and \(b\) (the base) must be positive and not equal to 1. Since 0 does not satisfy these conditions, \(\log_7(0)\) is undefined.
