How do I express these in scientific notation AND Log10 form?

1) ln(8.1)

2) 32.8 x 10^-2 + 3.15 x 10^-1

3) 10^-2 x 10^4.5

4) 10^-45

5) 8^2.34

I will be happy to critique your work here. Most of these require conversion. Do the math, and let your calculator do the log10 form.

If I knew how to do the math, I wouldn't have asked for help.
