Answer 1

`log_10 0.0856 ~= -1.0675`

Explanation:

Assuming the log is to base 10 and let the result be `x`

Then: `x=log_10 0.0856` (A)

This is equivalent to `10^x = 0.0856` (B)

(A) `x` can be found by normal scientific calculator to be `~=-1.0675`

and checked by (B) as: `10^-1.0675 ~= 0.0856`
