Question

How do you calculate `log_3 -4.8` with a calculator?

Answer 1

Assuming that you want to take the `log` of `-4.8` to the base `3`, this expression is mathematically invalid.

Explanation:

It is impossible to take the `log` of `x` where `x<=0`. This is because, for any non-zero constant, `x`, there is no power we can raise it to so that it becomes equal to or less than `0`.
