use the change of base formula to evaluate log877

Answer 1

To evaluate log877, we can use the change of base formula:

log a (x) = log b (x) / log b (a)

Let's choose the base 10 for the logs:

log877 = log10(877) / log10(10)

log(877) is roughly equal to 2.9444826721515.

Therefore, log877 ≈ 2.944.
