Use your log laws:
Unparseable latex formula:

\displaystyle \log_{10} \left(\frac{u_{100}}{u_{200}} \right) = \log_{10} u_{100} - \log_{10} u_{200}\right)



Now, this looks precisely like the result you've proven in c(ii), except that n=100n=100.

So, using your answer to part c(ii), what would log⁡10u100−log⁡10u200 \log_{10} u_100 - \log_{10} u_{200} be?

(Remember that it's just c(ii) with n=100n=100)

Edit: too late, sorry Sean!

Hey, let me make something clear: if I ever give you my socks, it's because I want you to wash them. Got it, spank?
