So, I took an exam on conversion of units in chemistry and I put a negative exponent on the bottom:(adsbygoogle = window.adsbygoogle || []).push({});

100s* 1nanoseconds/10^-9s = 10^11 ns,

Is this wrong? If it's possible in math, why not in chemistry? My professor marked all my answers wrong due to this. Is there any way to argue my reasoning? Thanks in advance.
