Example (with steps)1. Find Negative log(0.0001), base=10
Solution: `-log_(10)(0.0001)=-(-4)=4`
2. Find Negative log(2), base=10
Solution: `-log_(10)(2)=-(0.301)=-0.301`
3. Find Negative log(5), base=5
Solution: `-log_(5)(5)=-(log_(10)(5))/(log_(10)(5))=-(0.699)/(0.699)=-(1)=-1`
4. Find Negative log(5), base=e
Solution: `-log_(e)(5)=-ln(5)=-(1.6094)=-1.6094`
