(1.00 x 10^5)NM - (3.96 x 10^3) NM = ?
I think that since they're both NM don't you think that you can just subtract them?
96,040 NM whatever NM stands for, and I didn't factor in significant figures.
Isn't that nanometers..Dr.Bob?
I have no idea but nanometers is nm, not NM. I think NM is New Mexico.
Its nanometers my bad
OK. Watch the significant figures.
