How do I express these in scientific notation AND Log10 form?
2) 32.8 x 10^-2 + 3.15 x 10^-1
3) 10^-2 x 10^4.5
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.
